Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and more particularly to an interference-proof outdoor distribution box. Background Art

[0002] The distribution box is a low-voltage distribution device that is assembled in a closed or semi-closed metal cabinet with switchgear, measuring instruments, protective electrical appliances and auxiliary equipment according to the electrical wiring requirements. With the development of modern society, the demand for distribution boxes is increasing, so the staff is required to regularly inspect and maintain the distribution box as a whole. The outdoor anti-interference distribution box is an electrical distribution equipment specially used in outdoor environments. It is mainly used to ensure the stability and safety of the power system under various environmental conditions without being interfered by the external environment.

[0003] The outdoor anti-interference distribution box in the prior art mainly adopts a fully sealed or semi-sealed structure to prevent external rain and dust from entering the distribution box, thereby ensuring that the internal equipment is not affected by environmental factors. However, there are many electrical components installed inside the distribution box. These electrical components will generate a lot of heat when working. When the heat accumulates too much, it is not conducive to the operation of the distribution box, and it will also affect the working performance of the electrical components. Moreover, when the external environment is relatively cold, the internal temperature of the distribution box is higher than the external temperature of the distribution box. At this time, condensation water will be generated on the inner wall of the distribution box. When the condensation water slides from the inner wall of the distribution box to the electrical components, the electrical components will be affected by the condensation water, causing the electrical components to short-circuit. For this reason, the prior art generally adds a fan to the distribution box to force ventilation of the distribution box, but the fan will generate noise and vibration when forcibly ventilating the distribution box. The vibration of the fan may affect the stability of the distribution box, and seriously affect the stability of the electrical components inside the distribution box, causing the wire connections between the electrical components to fall off, thereby causing the electrical components to short-circuit.

[0004] In view of the above situation, the present invention designs an interference-proof outdoor distribution box to solve the above technical problems. Summary of the invention

[0015] Beneficial effects of the present invention: 1. The present invention provides an interference-proof outdoor distribution box. The device uses an air inlet arranged on the distribution box body to allow external cold air to flow into the distribution box through a guide plate, thereby driving the circulation component to move through the gas itself. When the circulation component is driven by the gas to rotate, the high-temperature gas inside the distribution box can be brought out. When the high-temperature gas is discharged, the guide member arranged on the top of the device body changes the flow direction of the high-temperature gas, thereby discharging the high-temperature gas, thereby avoiding the backflow of the high-temperature gas. At the same time, it can avoid the backflow of the high-temperature gas and gather inside the distribution box, resulting in the phenomenon of condensed water due to the excessive temperature difference between the inside and outside of the distribution box. In addition, the setting of the double-layer box can ensure that the overall impact resistance of the distribution box is strong, and can avoid the influence of external pressure on the inside of the distribution box.

[0016] 2. The present invention provides an interference-proof outdoor distribution box. The device is equipped with a circulation component. Since the circulation component is arranged above the inner box body, when the temperature inside the inner box body is high, the high-temperature gas drives the circulation component to rotate by utilizing the principle of upward flow of high-temperature gas. The circulation component brings out the high-temperature gas inside the inner box body to ensure that the temperature difference between the inside and outside of the distribution box is not large, thereby avoiding the generation of condensation water on the inner wall of the distribution box, and further avoiding the phenomenon of short circuit of electrical components inside the distribution box caused by condensation water.

[0017] 3. The present invention provides an interference-proof outdoor distribution box. The device cooperates with a control component through a circulation component. When the electrical components inside the distribution box generate a lot of heat, the control component can absorb the high-temperature gas in the inner box body, and then discharge the high-temperature gas from the inner box body to the installation cavity. The gas flow rate in the installation cavity increases, which increases the rotation speed of the circulation component. The circulation component can accelerate the discharge of the high-temperature gas in the inner box body, thereby ensuring that the temperature difference between the inside and outside of the distribution box is not too large, thereby avoiding the generation of condensed water and causing short circuits in electrical components.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0028] refer to Figure 1 , Figure 2 , Figure 3 , an anti-interference outdoor distribution box, used to prevent the outdoor environment from causing damage to the internal electrical components of the distribution box, including a device body 1, a plurality of air inlets 11 are opened at both sides of the bottom of the device body 1, and a shielding plate 12 is arranged above each air inlet 11, the shielding plate 12 is used to prevent rainwater from flowing into the device body 1 along the outside of the device body 1, a wiring port 13 is opened at the bottom of the device body 1, an air outlet is opened at the top of the device body 1, and a guide 14 is arranged above the air outlet, and a box door 15 for sealing the internal electrical components is rotatably arranged on one side of the device body 1; the device body 1 is divided into an outer box body 2 and an inner box body 21, and the outer box body 2 and the inner box body 21 are connected to each other. An installation cavity 22 is formed in the inner layer box body 21, and an exhaust port 211 is opened at the top of the inner layer box body 21, and guide plates 221 are symmetrically arranged in the installation cavity 22, and the guide plates 221 are arranged above the air inlet 11, and one end of the guide plates 221 is rotatably connected to the inner wall of the outer layer box body 2; a fixed support plate 141 is arranged above the inner layer box body 21, and a circulation component 3 is penetrated through the fixed support plate 141, and the circulation component 3 is rotatably connected to the fixed support plate 141, and the external air enters the installation cavity 22 through the air inlet 11, and the gas drives the circulation component 3 to rotate, so that the high-temperature gas generated by the electrical components installed in the inner layer box body 21 is brought out, and the exhaust gas of the inner layer box body 21 changes its flow direction through the guide member 14.

[0029] During operation, in order to avoid excessive temperature difference between the inside and outside of the distribution box, the principle of gas convection is used. When there is a temperature difference between the inside and outside of the distribution box, natural convection of the gas will occur. At this time, the high-temperature gas inside the inner box 21 will rise. When the high-temperature gas rises, the high-temperature gas will drive the circulation component 3 to rotate. At this time, the circulation component 3 can discharge the high-temperature gas inside the inner box 21, and guide the high-temperature gas discharged from the inner box 21 to the surface of the guide 14 through the guide 14 opened on the top of the equipment body 1, so that the high-temperature gas flows out to the outside along the surface of the guide 14, thereby avoiding the backflow of the high-temperature gas, causing the high-temperature gas to gather in the inner box 21, so that the temperature difference between the inside and outside of the distribution box is too large, thereby generating condensation water on the inner wall of the distribution box, and then causing the condensation water to affect the electrical components. When the high-temperature gas inside the inner box 21 rises, the cold air on the outside of the distribution box passes through the equipment body 1. The air inlet 11 opened on the outside of the body 1 enters the installation cavity 22, and the cold air flows upward through the installation cavity 22. At this time, the cold air pushes the guide plate 221 to flow upward. The cold air hits the guide plate 221 and some impurities in the cold air will gather on the guide plate 221. When the impurities in the cold air gather to a certain extent, the impurities will remain at the bottom of the installation cavity 22. After working for a long time, the operator manually cleans the internal impurities to avoid excessive impurities from affecting the electrical components inside the distribution box. After the cold air passes through the guide plate 221, the high-temperature gas will drive the circulation component 3 to rotate during the rising process. When the cold air pushes the circulation component 3 to rotate, the rotation speed of the circulation component 3 will increase. At this time, the circulation component 3 will discharge the high-temperature gas in the inner box 21 more quickly, thereby ensuring that the temperature difference between the inside and outside of the distribution box is not too high, thereby avoiding the condensation water generated on the inner wall of the distribution box from affecting the electrical components.

[0030] refer to Figure 4 , Figure 5 , Figure 6 The guide member 14 includes a support plate 141 and a guide block 142. The top of the outer box body 2 is a frustum structure, and a support plate 141 is arranged above the outer box body 2. A guide block 142 is arranged on the support plate 141, and the guide block 142 is a hollow structure. The guide block 142 and the top of the outer box body 2 are conical structures. The conical structure of the guide block 142 allows the exhaust gas to flow along the inner wall of the guide block 142.

[0031] When high-temperature gas and cold air flow out from the air outlet opened at the top of the equipment body 1, the gas will hit the hollow position of the guide block 142. At this time, the gas will spread around the hollow part of the guide block 142, and then the gas will adhere to the inner wall of the guide block 142 and flow out to the outside. Through the setting of the frustum structure of the outer box body 2, when there is rain and snow in the external environment, the rain and snow will flow along the surface of the frustum structure to avoid the accumulation of rain and snow and the phenomenon of excessive pressure on the distribution box. The conical structure of the guide block 142 can gather high-temperature gas. When the temperature difference is large, the formed condensed water will slide along the inner wall of the guide block 142, and the condensed water will fall on the top of the outer box body 2 through the guide block 142. The condensed water slides along the conical structure surface of the outer box body 2 to the bottom surface, ensuring that the distribution box will not be affected by the condensed water and cause damage to the electrical components.

[0032] The circulation component 3 includes a wind wheel 31, a rotating shaft 32 and a cylinder 33. The rotating shaft 32 passes through a fixed support plate 141 opened above the inner box body 21, and wind wheels 31 are arranged at both ends of the rotating shaft 32. A cylinder 33 is arranged in the middle position of the rotating shaft 32. The cylinder 33 is arranged above the exhaust port 211, and the diameter of the cylinder 33 is consistent with the width of the exhaust port 211. A ventilation hole 331 is opened on the surface of the cylinder 33.

[0033] During operation, when the external cold air moves upward, the cold air pushes the wind wheel 31 to rotate. Since the wind wheel 31 is fixedly connected to the rotating shaft 32, and the rotating shaft 32 is rotatably connected to the fixed support plate 141 above the inner box 21, the rotation of the wind wheel 31 drives the rotating shaft 32 to rotate. At this time, the rotating shaft 32 drives the cylinder 33 to rotate. When the high-temperature gas flows out to the outside through the ventilation holes 331 on the cylinder 33, the rotation of the cylinder 33 can avoid the backflow of the high-temperature gas, thereby preventing the high-temperature gas from refluxing and gathering inside the inner box 21.

[0034] A plurality of ventilation holes 331 are provided in a circular array on the circumferential surface of the cylinder 33, and the ventilation holes 331 are arranged throughout the cylinder 33. The ventilation holes 331 are conical structures with an outer diameter smaller than an inner diameter. The arrangement of the conical structure ventilation holes 331 can speed up the passage of high-temperature gas. At the same time, since the outer diameter of the ventilation holes 331 is smaller than the inner diameter, the phenomenon of backflow and aggregation of external gas and high-temperature gas can be prevented to a greater extent, thereby accelerating the discharge of high-temperature gas on the one hand, and preventing the accumulation of high-temperature gas to produce condensed water and cause damage to electrical components on the other hand.

[0035] The rotating shaft 32 is provided with a rotating blade 321, and the rotating blade 321 is arranged on the inner wall of the cylinder 33. One end of the rotating blade 321 is connected to the rotating shaft 32, and the other end of the rotating blade 321 is arranged in contact with the inner wall of the inner cylinder. The rotating direction of the rotating blade 321 is consistent with the rotating direction of the wind wheel 31. Through such a configuration, when the high-temperature gas rises and pushes the rotating blade 321, the rotating blade 321 rotates. At this time, the rotating blade 321 can drive the rotation of the cylinder 33 and the wind wheel 31. When the rotation speed of the wind wheel 31 is accelerated, the gas inside the installation cavity 22 will flow to the outside faster, and the cold air outside will also flow into the installation cavity 22 faster. At this time, the flow of the overall gas inside the distribution box can be accelerated, thereby maximally avoiding the situation where the temperature difference between the inside and outside of the distribution box is too large. At the same time, the same rotation direction can prevent the cold air from pushing the impeller and the high-temperature gas from pushing the rotating blade 321 to rotate in different directions, resulting in the rotation of the rotating shaft 32 being blocked, thereby failing to accelerate the flow of gas inside the distribution box, resulting in the accumulation of gas inside the distribution box to produce condensed water.

[0036] The installation cavity 22 is provided with a control assembly 4, and the control assembly 4 includes a partition plate 41, a flow cavity 42, a partition plate 43, a telescopic member 44, a push plate 45, an air outlet 46, a one-way valve 47 and a sealing member 48. The partition plate 41 divides the installation cavity 22 into two parts, and the partition plate 41 and the outer side surface of the inner box body 21 form a flow cavity 42. The flow cavity 42 is divided into two parts by the partition plate 43, and the partition plate 43 is an "L"-shaped structure. The bottom of the flow cavity is provided with A telescopic member 44, and one end of the telescopic member 44 is connected to the bottom of the flow chamber, and the other end of the telescopic member 44 is connected to a push plate 45, the inner layer box body 21 is provided with an air inlet of the flow chamber 42 on the side close to the flow chamber 42, and the air inlet of the flow chamber 42 is symmetrically arranged up and down, and a sealing member 48 for sealing the air inlet of the flow chamber 42 is arranged in the air inlet of the flow chamber 42, and a plurality of air outlets 46 are opened above the partition plate 43 and the partition plate 41, and a check valve 47 is arranged inside the plurality of air outlets 46.

[0037] During operation, when the electrical components inside the distribution box generate high heat, the high-temperature gas in the inner box 21 cannot be quickly and effectively discharged through the circulation component 3. At this time, the telescopic rod is started, and the telescopic rod reciprocates up and down. When the telescopic rod moves upward, the seal 48 above the inner box 21 is squeezed and closed by the gas inside the flow chamber, and the gas inside the flow chamber is blown toward the wind wheel 31 through the air outlet 46. The seal 48 below the inner box 21 is pushed open by the high-temperature gas, and the high-temperature gas flows into the flow chamber. When the telescopic rod moves downward, the seal 48 below the inner box 21 is squeezed and closed by the gas inside the flow chamber, and the gas just flowing into the flow chamber The high-temperature gas is blown toward the wind wheel 31, and the seal 48 above the inner box body 21 is pushed open by the high-temperature gas, and the high-temperature gas flows into the flow cavity. Since the partition plate 43 and the partition plate 41 have multiple air outlets 46, at least one of the air outlets 46 is connected, it can prevent the gas below the flow cavity from flowing into the upper part of the flow cavity, resulting in excessive gas accumulation above the flow cavity and excessive pressure when the push plate 45 moves upward. At the same time, the one-way valve 47 arranged in the air outlet 46 can prevent the gas from flowing back, and the gas blown toward the wind wheel 31 can accelerate the rotation of the rotating shaft 32, thereby accelerating the discharge of the high-temperature gas in the inner box body 21 from the inside to the outside.

[0038] refer to Figure 7 , Figure 8 The sealing member 48 includes a fixing ring 481 and a sealing blade 482. The fixing ring 481 is arranged in the air inlet of the circulation chamber 42, and a plurality of sealing blades 482 are arranged in an annular manner on the fixing ring 481. The sealing blade 482 is rotatably connected to the fixing ring 481. Through such an arrangement, when the gas flows from the inner box body 21 to the flow chamber, the sealing blade 482 can be pushed to open, so that the gas flows into the flow chamber. When the gas flows in the direction, the gas pushes the sealing blade 482 to seal the air inlet of the flow chamber, thereby avoiding the gas backflow phenomenon and ensuring the stability of the overall equipment operation.

[0039] The sealing blades 482 are made of rubber material, and multiple sealing blades 482 fit together to completely seal the air inlet of the flow chamber 42. The gas pushes the sealing blades 482 to move the gas from the inner box 21 to the inside of the flow chamber. The rubber sealing blades 482 can fit better with each other, thereby ensuring the sealing of the air inlet of the flow chamber. At the same time, the rubber sealing blades 482 will not cause damage to the inner box 21 when rotating.

[0040] The telescopic member 44 drives the push plate 45 to reciprocate up and down, and the push plate 45 is in contact with the inner walls of the flow chamber and the partition plate 43 on all sides. The moving distance of the push plate 45 is smaller than the distance between the two seals 48. The close fit of the push plate 45 can ensure that the gas will not leak between the push plate 45 and the inner walls of the flow chamber and the partition plate 43. At the same time, the moving distance of the push plate 45 is smaller than the distance between the two seals 48 to ensure the stable operation of the equipment and avoid damage to the seal 48 during movement, which may cause the seal 48 to fall off, thereby further ensuring the stability of the equipment operation.

[0041] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
