Description

Technical Field

[0001] The invention relates to the technical field of junction box equipment, in particular to a junction box used for a bus duct. Background Art

[0002] As a new type of distribution conductor, bus duct is used for the main line of power transmission in the field of power transmission trunk lines. It is a closed metal device composed of copper and aluminum busbar columns. It is used to distribute large power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. Most of the bus duct junction boxes are designed for indoor installation, but in some special cases, the junction boxes can also be designed as outdoor equipment. In order to cope with the external environment, the outdoor junction box requires a higher level of protection.

[0003] Coastal areas, especially southern coastal cities, will have a long rainy season from June to July each year. The outer shell of the junction box is mostly made of metal. After being roasted at high temperature and then cooled by external rain water, the junction box will be affected by the alternating hot and cold weather, and tiny water droplets will condense inside the junction box, increasing the moisture content of the air inside the junction box, which is likely to cause corrosion at the terminal. To address the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a branch box for a bus duct, comprising a support mechanism, the support mechanism also comprising a shell, the top of the shell is fixedly connected to an air inlet box, one end of the support mechanism control mechanism shell is fixedly connected to a fixed plate, the inner wall of the fixed plate is slidably connected to a slider, the bottom of the fixed plate is fixedly connected to a CNC telescopic rod, and the bottom of the slider is fixedly connected to a folding plate; The control mechanism comprises an inclined surface block fixedly connected to the top of the housing, a sliding frame slidably connected to the inner wall of the inclined surface block, a windshield plate slidably connected to the inner wall of the sliding frame, and a slide plate fixedly connected to the bottom of the windshield plate; The limiting mechanism comprises a rotating plate rotatably connected to the inner wall of the through hole at the bottom of the shell, a sliding rod is fixedly connected to the bottom of the slide plate, and an end of the sliding rod away from the slide plate is rotatably connected to the top of the rotating plate.

[0005] Preferably, the supporting mechanism also includes a U-shaped slide fixedly connected to the inner wall of the shell, a return spring is fixedly connected to the outer wall of the U-shaped slide, and one end of the return spring away from the U-shaped slide is fixedly connected to the bottom of the slide. Taking advantage of the fact that the air velocity increases before rainfall in the plum rain season, an inclined block and a folding plate are arranged inside the device. Before using the device, the device is installed at the desired position, and the power of the waterproof switch is turned on. When the external wind speed increases, the CNC telescopic rod will receive power from the control mechanism, and the CNC telescopic rod will generate an outward extension force. At this time, the force applied by the CNC telescopic rod will act on the folded position of the folding plate, so that the folding plate appears as follows Figure 5 In the state shown, as the folding plate is folded downward, the lowest point of the folding plate will contact the top of the wind deflector, forcing the wind deflector to drive the bottom slide plate to slide downward, so that a gap is formed between the slide plate and the shell, and the air flowing into the bellows can pass through Figure 5 The route G in the middle enters the interior of the shell; in addition, when the slide plate moves downward, the slide plate drives the sliding rod to push the rotating plate to rotate downward, so that a gap for air outlet is formed between the rotating plate and the shell. At this time, the air entering the shell through route G will carry most of the hot air inside the shell and be discharged outward through the gap of the fixed plate. Through the application of the above components, the internal temperature of the shell can be slowly lowered before it rains, and the temperature of the shell itself can be quickly lowered, so as to avoid the shell being affected by the external cold and the internal heat, and the appearance of small water droplets inside the equipment shell, thereby increasing the air humidity inside the equipment and causing rust on the terminal.

[0006] Preferably, the supporting mechanism also includes a pushing spring fixedly connected to the side wall of the slider, a wiring device fixedly connected to the inner wall of the shell, a box cover rotatably connected to the inner wall of the side wall through hole of the shell, and a fixing frame fixedly connected to the side wall of the shell. When the folding plate and the inclined plane block form an angle state, before the external air enters the shell through the G route, the restricted inclined plane block and the folding plate form a bell mouth, and when the air enters the contraction part from the expansion part, the air speed will increase due to the reduction in the cross-sectional area of ​​the contraction part, thereby accelerating the outflow speed of the hot air inside the shell, avoiding the short interval between strong wind and rainfall, which affects the cooling efficiency of the shell.

[0007] Preferably, the control mechanism also includes a waterproof switch fixedly connected to the top of the fixed plate, the top of the fixed plate is fixedly connected to a universal wheel base frame, the inner wall of the universal wheel base frame is rotatably connected to a ball bearing, the outer wall of the ball bearing is rotatably connected to a steering wheel top frame, and the top of the steering wheel top frame is fixedly connected to a fixing rod.

[0008] Preferably, the control mechanism also includes a cross wind-receiving plate fixedly connected to the outer wall of the fixed rod, four sliding cleaning knives are slidably connected to the outer wall of the cross wind-receiving plate, rubber rods are fixedly connected to the side walls of the four sliding cleaning knives, one end of the rubber rod away from the sliding cleaning knife is fixedly connected to the top of the universal wheel base, a sliding long rod is slidably connected to the inner wall of the through hole on the outer wall of the universal wheel base, a spring is fixedly connected to the outer wall of the sliding long rod, and a waterproof wire is fixedly connected to the side wall of the waterproof switch. Taking advantage of the high wind speed in the above-mentioned environment, a cross wind-receiving plate is arranged inside the equipment. When external wind flow acts on the outer wall of the cross wind-receiving plate, the cross wind-receiving plate will drive the fixed rod to tilt in one direction, and the fixed rod drives the bottom steering wheel top frame to tilt in the same direction, forcing the steering wheel top The bottom of the frame contacts the top of the sliding long rod, and the force of the inclination of the cross wind-receiving plate acts on the top of the waterproof switch through the sliding long rod, so that the waterproof switch transmits power to the waterproof wire, and the waterproof wire transmits power to the CNC telescopic rod. Utilizing the characteristics of the cross wind-receiving plate swinging in the wind, a sliding cleaning knife and a rubber rod are arranged inside the equipment, wherein the length of the restricted rubber rod is fixed and cannot be changed. When the cross wind-receiving plate tilts in one direction, the sliding cleaning knife in the other direction is pulled by the rubber rod, forcing the sliding cleaning knife to slide along the outer wall of the cross wind-receiving plate to clean the outer wall of the cross wind-receiving plate. Through the application of the above components, the accumulation of impurities on the outer wall of the cross wind-receiving plate can be effectively avoided, which affects the generation of impurities such as moss on the outer wall of the cross wind-receiving plate and affects the reaction efficiency of the equipment.

[0009] Preferably, the limiting mechanism further comprises a rolling column rotatably connected to the inner wall of the waterproof box, the top of the rolling column is fixedly connected to the water receiving box, and a through hole is provided at the bottom of the water receiving box.

[0010] Preferably, the limiting mechanism also includes a contact frame fixedly connected to the outer wall of the rolling column, and the end of the contact frame away from the rolling column is fixedly connected to a power connection block, and the side wall of the power connection block is fixedly connected. Utilizing the characteristic that the above-mentioned current is transmitted to the CNC telescopic rod through the waterproof wire, a power connection block is arranged inside the device. As the external environment changes from the windy stage to the rainy stage, external rainwater will act on the inside of the water receiving box. At this time, the water receiving box will receive part of the rainwater, thereby increasing its own weight. When the rainwater inside the water receiving box accumulates to a certain extent, the water receiving box will tilt, and the inclination force of the water receiving box drives the contact frame and the power connection block at the other end to lift upward through the rolling column, so that the power connection block is away from the waterproof wire, and the power transmission line of the waterproof wire is physically cut off. After the CNC telescopic rod loses power, the slide plate loses pressure, and will block the through holes at the top and bottom of the shell, so that the device is re-closed. Through the application of the above-mentioned components, it is avoided that the control mechanism comes into contact when the external environment continues to rain, resulting in the upper and lower through holes being in an open state in a heavy rain environment, causing external rainwater to splash into the inside of the shell, causing a short circuit in the line.

[0011] Preferably, the limiting mechanism also includes a support rod fixedly connected to the side wall of the waterproof box, the support rod having an end away from the waterproof box with a rotating rod, and the rotating rod having an end away from the support rod is fixedly connected to a T-shaped sealing plate, the outer wall of the T-shaped sealing plate is slidably connected to the inner wall of the through hole at the bottom of the water receiving box, and utilizing the characteristic of the above-mentioned water receiving box moving downward under pressure, a T-shaped sealing plate is arranged inside the equipment, when there is too much water flow inside the water receiving box, the water receiving box moves downward, so that the through hole of the water receiving box and the T-shaped sealing plate are misaligned to form a gap, and rainwater inside the water receiving box will slowly flow out through the above-mentioned gap, and when it continues to rain outside, the total amount of water inside the water receiving box is continuously supplemented by the outside world, and the water receiving box is always in a state of downward pressure, and after the rain stops, the water source inside the water receiving box is quickly discharged outward through the gap of the T-shaped sealing plate due to the lack of supplementation from the external environment, and the water receiving box is reset, and the power connection block is reset under the drive of the pulling spring, so that the power connection block and the waterproof wire are in a connected state.

[0012] The present invention has the following beneficial effects: (1) The present invention utilizes the characteristic that the air velocity increases before rainfall in the plum rain season. An inclined block and a folding plate are arranged inside the device. Before using the device, the device is installed at the desired position and the power of the waterproof switch is turned on. When the external wind speed increases, the CNC telescopic rod will receive the power from the control mechanism, and the CNC telescopic rod will generate an outward extension force. At this time, the force applied by the CNC telescopic rod will act on the folding position of the folding plate, so that the folding plate presents as shown in FIG. Figure 5 In the state shown, as the folding plate is folded downward, the lowest point of the folding plate will contact the top of the wind deflector, forcing the wind deflector to drive the bottom slide plate to slide downward, so that a gap is formed between the slide plate and the shell, and the air flowing into the bellows can pass through Figure 5 The route G in the middle enters the interior of the shell; in addition, when the slide plate moves downward, the slide plate drives the sliding rod to push the rotating plate to rotate downward, so that a gap for air outlet is formed between the rotating plate and the shell. At this time, the air entering the shell through route G will carry most of the hot air inside the shell and be discharged outward through the gap of the fixed plate. Through the application of the above components, the internal temperature of the shell can be slowly lowered before it rains, and the temperature of the shell itself can be quickly lowered, so as to avoid the shell being affected by the external cold and the internal heat, and the appearance of small water droplets inside the equipment shell, thereby increasing the air humidity inside the equipment and causing rust on the terminal.

[0013] (2) The present invention utilizes the above-mentioned characteristic of relatively fast wind speed in the environment, and a cross wind plate is arranged inside the device. When the external wind flow acts on the outer wall of the cross wind plate, the cross wind plate will drive the fixed rod to tilt in one direction, and the fixed rod drives the bottom steering wheel top frame to tilt in the same direction, forcing the bottom of the steering wheel top frame to contact the top of the sliding long rod. The force of the tilting of the cross wind plate acts on the top of the waterproof switch through the sliding long rod, so that the waterproof switch transmits electricity to the waterproof wire, and the waterproof wire transmits electricity to the CNC telescopic rod. Utilizing the characteristic of the cross wind plate swinging in the wind, a sliding cleaning knife and a rubber rod are arranged inside the device, wherein the length of the restricted rubber rod is fixed and cannot be changed. When the cross wind plate tilts in one direction, the sliding cleaning knife in the other direction is pulled by the rubber rod, forcing the sliding cleaning knife to slide along the outer wall of the cross wind plate to clean the outer wall of the cross wind plate. Through the application of the above-mentioned components, it is effectively avoided that impurities accumulate on the outer wall of the cross wind plate, which affects the generation of impurities such as moss on the outer wall of the cross wind plate and affects the reaction efficiency of the device.

[0014] (3) The present invention utilizes the characteristic that the above-mentioned current is transmitted to the CNC telescopic rod through the waterproof wire, and a power connection block is arranged inside the device. As the external environment changes from the windy stage to the rainy stage, the external rainwater will act on the inside of the water receiving box. At this time, the water receiving box will receive part of the rainwater, thereby increasing its own weight. When the rainwater inside the water receiving box accumulates to a certain extent, the water receiving box will tilt, and the force of the tilt of the water receiving box drives the contact frame and the power connection block at the other end to lift upward through the rolling column, so that the power connection block is away from the waterproof wire, and the power transmission line of the waterproof wire is physically cut off. After the CNC telescopic rod loses power, the slide plate loses pressure and will block the through holes at the top and bottom of the shell, so that the device is closed again. Through the application of the above-mentioned components, it is avoided that the control mechanism comes into contact with the external environment when it rains continuously, resulting in the upper and lower through holes being in an open state under heavy rain conditions, causing external rainwater to splash into the inside of the shell, causing a short circuit in the line.

[0015] (4) The present invention utilizes the characteristic that the water receiving box moves downward under pressure, and a T-shaped sealing plate is arranged inside the device. When there is too much water flow inside the water receiving box, the water receiving box moves downward, so that the through hole of the water receiving box and the T-shaped sealing plate are misaligned, forming a gap, and the rainwater inside the water receiving box will slowly flow out through the above gap. When it continues to rain outside, the total amount of water inside the water receiving box is constantly supplemented by the outside world, and the water receiving box is always in a downward pressure state. After the rain stops, the water source inside the water receiving box quickly flows out through the T-shaped sealing plate because there is no supplement from the external environment. The water receiving box is reset by being discharged outward through the gap, and the power receiving block is reset under the drive of the pulling spring, so that the power receiving block and the waterproof wire are in a connected state; in addition, when the folding plate and the inclined plane block form an angle state, before the external air enters the shell through the G route, the restricted inclined plane block and the folding plate form a bell mouth, and when the air enters the contraction part from the expansion part, the air speed will increase due to the reduction of the cross-sectional area of ​​the contraction part, thereby accelerating the outflow speed of the hot air inside the shell, avoiding the short interval between strong wind and rainfall, which affects the cooling efficiency of the shell.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figure 1 - Figure 5 The present invention is a branch box for a bus duct, comprising a support mechanism 1, the support mechanism 1 further comprising a shell 11, the top of the shell 11 is fixedly connected to an air inlet box 12, the support mechanism 1 controls the mechanism 2, one end of the shell 11 is fixedly connected to a fixed plate 13, the inner wall of the fixed plate 13 is slidably connected to a slider 14, the bottom of the fixed plate 13 is fixedly connected to a CNC telescopic rod 15, and the bottom of the slider 14 is fixedly connected to a folding plate 16; The control mechanism 2 includes a ramp block 21 fixedly connected to the top of the housing 11, a sliding frame 22 is slidably connected to the inner wall of the ramp block 21, a windshield plate 23 is slidably connected to the inner wall of the sliding frame 22, and a slide plate 24 is fixedly connected to the bottom of the windshield plate 23; The limiting mechanism 3 includes a rotating plate 31 rotatably connected to the inner wall of the through hole at the bottom of the shell 11, a sliding rod 32 is fixedly connected to the bottom of the slide plate 24, and one end of the sliding rod 32 away from the slide plate 24 is rotatably connected to the top of the rotating plate 31.

[0021] The support mechanism 1 also includes a U-shaped slide 17 fixedly connected to the inner wall of the shell 11, and a return spring 18 is fixedly connected to the outer wall of the U-shaped slide 17. The end of the return spring 18 away from the U-shaped slide 17 is fixedly connected to the bottom of the slide 24. Taking advantage of the fact that the air flow rate increases before rainfall in the plum rain season, an inclined block 21 and a folding plate 16 are arranged inside the device. Before using the device, the device is installed at the desired position, and the power of the waterproof switch 25 is turned on. When the external wind speed increases, the CNC telescopic rod 15 will receive the power from the control mechanism 2, and the CNC telescopic rod 15 will generate an outward extension force. At this time, the force applied by the CNC telescopic rod 15 will act on the folded position of the folding plate 16, so that the folding plate 16 appears as follows Figure 5 In the state shown, as the folding plate 16 is folded downward, the lowest point of the folding plate 16 will contact the top of the wind shield 23, forcing the wind shield 23 to drive the bottom slide plate 24 to slide downward, so that a gap is formed between the slide plate 24 and the shell 11, and the air flowing into the bellows 12 can pass through Figure 5 In addition, when the slide plate 24 moves downward, the slide plate 24 drives the sliding rod 32 to push the rotating plate 31 to rotate downward, so that a gap for air outlet is formed between the rotating plate 31 and the shell 11. At this time, the air entering the shell 11 through the route G will carry most of the hot air inside the shell 11 and be discharged outward through the gap of the fixed plate 13. Through the application of the above components, the internal temperature of the shell 11 can be slowly lowered before it rains, and the temperature of the shell 11 itself can be quickly lowered, so as to avoid the shell 11 being affected by the external cold and the internal heat, and the appearance of small water droplets inside the device shell 11, thereby increasing the air humidity inside the equipment and causing rust on the terminal.

[0022] The support mechanism 1 also includes a push spring 19 fixedly connected to the side wall of the slider 14, a wiring device 110 fixedly connected to the inner wall of the shell 11, a box cover 111 is rotatably connected to the inner wall of the side wall through hole of the shell 11, and a fixing frame 112 is fixedly connected to the side wall of the shell 11. When the folding plate 16 and the inclined block 21 form an angle state, before the external air enters the shell 11 through the G route, the restricted inclined block 21 and the folding plate 16 form a bell mouth. When the air enters the contraction part from the expansion part, the air speed will increase due to the reduction in the cross-sectional area of ​​the contraction part, thereby accelerating the outflow speed of the hot air inside the shell 11, avoiding the short interval between strong wind and rainfall, which affects the cooling efficiency of the shell 11.

[0023] For example 2, please refer to Figure 6 - Figure 8The present invention is a junction box for a bus duct. On the basis of the first embodiment, the control mechanism 2 also includes a waterproof switch 25 fixedly connected to the top of the fixed plate 13, and the top of the fixed plate 13 is fixedly connected to a universal wheel base frame 26, and the inner wall of the universal wheel base frame 26 is rotatably connected to a ball bearing 27, and the outer wall of the ball bearing 27 is rotatably connected to a steering wheel top frame 28, and the top of the steering wheel top frame 28 is fixedly connected to a fixing rod 29.

[0024] The control mechanism 2 also includes a cross wind-receiving plate 210 fixedly connected to the outer wall of the fixed rod 29, four sliding cleaning knives 213 are slidably connected to the outer wall of the cross wind-receiving plate 210, and rubber rods 211 are fixedly connected to the side walls of the four sliding cleaning knives 213, and the end of the rubber rod 211 away from the sliding cleaning knife 213 is fixedly connected to the top of the universal wheel chassis 26, and a sliding long rod 212 is slidably connected to the inner wall of the through hole on the outer wall of the universal wheel chassis 26, and a spring is fixedly connected to the outer wall of the sliding long rod 212, and a waterproof wire 214 is fixedly connected to the side wall of the waterproof switch 25. Taking advantage of the high wind speed in the above-mentioned environment, a cross wind-receiving plate 210 is arranged inside the device. When the external wind flow acts on the outer wall of the cross wind-receiving plate 210, the cross wind-receiving plate 210 will drive the fixed rod 29 to tilt in one direction, and the fixed rod 29 drives the bottom steering wheel top frame 28 to tilt in the same direction, forcing the steering wheel top frame 28 The bottom is in contact with the top of the sliding long rod 212, and the force of the inclination of the cross wind-receiving plate 210 acts on the top of the waterproof switch 25 through the sliding long rod 212, so that the waterproof switch 25 transmits electricity to the waterproof wire 214, and the waterproof wire 214 transmits electricity to the CNC telescopic rod 15. Utilizing the characteristics of the cross wind-receiving plate 210 swinging in the wind, a sliding cleaning knife 213 and a rubber rod 211 are arranged inside the device, wherein the length of the restricted rubber rod 211 is fixed and cannot be changed. When the cross wind-receiving plate 210 tilts in one direction, the sliding cleaning knife 213 in the other direction is pulled by the rubber rod 211, forcing the sliding cleaning knife 213 to slide along the outer wall of the cross wind-receiving plate 210 to clean the outer wall of the cross wind-receiving plate 210. Through the application of the above components, it is effectively avoided that impurities accumulate on the outer wall of the cross wind-receiving plate 210, which affects the generation of impurities such as moss on the outer wall of the cross wind-receiving plate 210 and affects the reaction efficiency of the equipment.

[0025] The limiting mechanism 3 further includes a rolling column 34 rotatably connected to the inner wall of the waterproof box 33 , the top of the rolling column 34 is fixedly connected to a water receiving box 35 , and a through hole is opened at the bottom of the water receiving box 35 .

[0026] The limiting mechanism 3 also includes a contact frame 36 fixedly connected to the outer wall of the rolling column 34, and the end of the contact frame 36 away from the rolling column 34 is fixedly connected to a power receiving block 37, and a pulling spring 38 is fixedly connected to the side wall of the power receiving block 37. By utilizing the characteristic that the above-mentioned current is transmitted to the CNC telescopic rod 15 through the waterproof wire 214, a power receiving block 37 is arranged inside the device. As the external environment changes from the windy stage to the rainy stage, the external rainwater will act on the inside of the water receiving box 35. At this time, the water receiving box 35 will receive part of the rainwater, thereby increasing its own weight. When the rainwater inside the water receiving box 35 accumulates to a certain extent, the water receiving box 35 will tilt. The tilting force of the water receiving box 35 drives the contact frame 36 and the power receiving block 37 at the other end to be lifted upward through the rolling column 34, so that the power receiving block 37 is away from the waterproof wire 214, and the power transmission line of the waterproof wire 214 is physically cut off. After the CNC telescopic rod 15 loses power, the slide plate 24 loses pressure and will block the through holes at the top and bottom of the shell 11, so that the device is closed again. Through the application of the above-mentioned components, the control mechanism 2 is prevented from contacting the external environment when it rains continuously, resulting in the upper and lower through holes being in an open state in a heavy rain environment, causing external rainwater to splash into the inside of the shell 11, causing a short circuit in the line.

[0027] The limiting mechanism 3 also includes a support rod 39 fixedly connected to the side wall of the waterproof box 33, and a rotating rod 310 is rotatably connected to the end of the support rod 39 away from the waterproof box 33, and a T-shaped sealing plate 311 is fixedly connected to the end of the rotating rod 310 away from the support rod 39. The outer wall of the T-shaped sealing plate 311 is slidably connected to the inner wall of the through hole at the bottom of the water receiving box 35. By utilizing the characteristic that the water receiving box 35 moves downward under pressure, a T-shaped sealing plate 311 is arranged inside the device. When there is too much water flow inside the water receiving box 35, the water receiving box 35 moves downward, so that the through hole of the water receiving box 35 is in contact with the T The T-shaped sealing plate 311 is misaligned to form a gap, and the rainwater inside the water receiving box 35 will slowly flow out through the above-mentioned gap. When it continues to rain outside, the total amount of water inside the water receiving box 35 is constantly replenished by the outside world, and the water receiving box 35 is always in a downward pressure state. After the rain stops, the water source inside the water receiving box 35 is quickly discharged outward through the gap of the T-shaped sealing plate 311 due to the lack of external environment replenishment. The water receiving box 35 is reset, and the power connection block 37 is reset under the drive of the pulling spring 38, so that the power connection block 37 and the waterproof wire 214 are in a connected state.

[0028] A specific application of this embodiment is: before using the device, the device is installed at a desired location, and the power supply of the waterproof switch 25 is turned on. When the external wind speed increases, when the external wind flow acts on the outer wall of the cross wind receiving plate 210, the cross wind receiving plate 210 will drive the fixed rod 29 to tilt in one direction, and the fixed rod 29 drives the bottom steering wheel top frame 28 to tilt in the same direction, forcing the bottom of the steering wheel top frame 28 to contact the top of the sliding long rod 212, and the tilting force of the cross wind receiving plate 210 is exerted by the sliding long rod 212. It is used on the top of the waterproof switch 25, so that the waterproof switch 25 transmits power to the waterproof wire 214, and the waterproof wire 214 transmits power to the CNC telescopic rod 15. By utilizing the characteristics of the cross wind receiving plate 210 swinging in the wind, a sliding cleaning knife 213 and a rubber rod 211 are arranged inside the device. The CNC telescopic rod 15 will receive power from the control mechanism 2, and the CNC telescopic rod 15 will generate an outward extension force. At this time, the force applied by the CNC telescopic rod 15 will act on the folding position of the folding plate 16, so that the folding plate 16 presents as shown in FIG. Figure 5 In the state shown, as the folding plate 16 is folded downward, the lowest point of the folding plate 16 will contact the top of the wind shield 23, forcing the wind shield 23 to drive the bottom slide plate 24 to slide downward, so that a gap is formed between the slide plate 24 and the shell 11, and the air flowing into the bellows 12 can pass through Figure 5 In addition, when the slide plate 24 moves downward, the slide plate 24 drives the sliding rod 32 to push the rotating plate 31 to rotate downward, so that a gap for air outlet is formed between the rotating plate 31 and the shell 11. At this time, the air entering the shell 11 through the route G will carry most of the hot air inside the shell 11 and be discharged outward through the gap of the fixed plate 13. Through the application of the above components, the internal temperature of the shell 11 can be slowly lowered before it rains, and the temperature of the shell 11 itself can be quickly lowered, so as to avoid the shell 11 being affected by the external cold and the internal heat, and the appearance of small water droplets inside the device shell 11, thereby increasing the air humidity inside the equipment and causing rust on the terminal.

[0029] Among them, the length of the restricted rubber rod 211 is fixed and cannot be changed. When the cross wind plate 210 tilts in one direction, the sliding cleaning knife 213 in the other direction is pulled by the rubber rod 211, forcing the sliding cleaning knife 213 to slide along the outer wall of the cross wind plate 210 to clean the outer wall of the cross wind plate 210. Through the application of the above-mentioned components, the accumulation of impurities on the outer wall of the cross wind plate 210 can be effectively avoided, which will affect the generation of impurities such as moss on the outer wall of the cross wind plate 210 and affect the reaction efficiency of the equipment.

[0030] Taking advantage of the above-mentioned feature that the current is transmitted to the CNC telescopic rod 15 through the waterproof wire 214, a power receiving block 37 is arranged inside the device. As the external environment changes from the windy stage to the rainy stage, the external rainwater will act on the inside of the water receiving box 35. At this time, the water receiving box 35 will receive part of the rainwater, thereby increasing its own weight. When the rainwater inside the water receiving box 35 accumulates to a certain extent, the water receiving box 35 will tilt, and the tilting force of the water receiving box 35 drives the contact frame 36 at the other end and the power receiving block 37 to lift upward through the rolling column 34, so that the power receiving block 37 is away from the water receiving box 35. The waterproof wire 214 physically cuts off the power transmission line of the waterproof wire 214. After the CNC telescopic rod 15 loses power, the slide plate 24 loses pressure and will block the through holes at the top and bottom of the shell 11, so that the device is closed again. By using the above components, it is avoided that the control mechanism 2 is in contact with the external environment when it rains continuously, resulting in the upper and lower through holes being in an open state in a heavy rain environment, causing external rainwater to splash into the shell 11 and cause a short circuit. By utilizing the characteristic that the water receiving box 35 moves downward under pressure, a The T-shaped sealing plate 311, when there is too much water flow inside the water receiving box 35, the water receiving box 35 moves down, so that the through hole of the water receiving box 35 is misaligned with the T-shaped sealing plate 311, forming a gap, and the rainwater inside the water receiving box 35 will slowly flow out through the above gap. When it continues to rain outside, the total amount of water inside the water receiving box 35 is constantly replenished by the outside world, and the water receiving box 35 is always in a downward pressure state. After the rain stops, the water source inside the water receiving box 35 is quickly discharged out through the gap of the T-shaped sealing plate 311 due to the lack of external environment replenishment. The water receiving box 35 is reset, and the water source inside the water receiving box 35 is quickly discharged out through the gap of the T-shaped sealing plate 311. The power block 37 is reset under the drive of the pulling spring 38, so that the power block 37 and the waterproof wire 214 are in a connected state; in addition, when the folding plate 16 and the inclined block 21 form an angle state, before the external air enters the outer shell 11 through the G route, the restricted inclined block 21 and the folding plate 16 form a bell mouth, and when the air enters the contraction part from the expansion part, the cross-sectional area of ​​the contraction part is reduced, and the air speed will increase, thereby accelerating the outflow speed of the hot air inside the outer shell 11, avoiding the short interval between strong wind and rainfall, which affects the cooling efficiency of the outer shell 11.
