Description

Technical Field

[0001] The utility model relates to the technical field of dual-power rapid switching, in particular to a complete set of dual-power rapid switching devices. Background Technique

[0002] Power-consuming enterprises such as those in the petroleum, chemical, metallurgical, fiber, semiconductor chip manufacturing, etc. industries have extremely high requirements for the continuity and reliability of power supply due to their production nature, technological processes, and product characteristics. Currently, a large amount of operating experience shows that when short-circuit faults, open-circuit faults (unauthorized tripping), etc. occur in the power supply systems or upstream systems of such enterprises, it will lead to the phenomenon of "voltage sag" in the voltage of the entire system, which is very likely to cause some production equipment sensitive to voltage to be forced to stop production, and in severe cases, it may even cause safety production accidents such as equipment damage and leakage of toxic and harmful materials. When the upstream power supply loses power or a short-circuit fault occurs on the system power supply side, even if the protection operates normally, it will cause a voltage dip time of about 100 ms. During the "voltage sag" period of about 100 ms, some control devices such as AC contactors, solenoid valves, and relays that control important production equipment are de-energized and released, and voltage-sensitive devices such as frequency converters are protected from low voltage and shut down, resulting in accidents where important production equipment stops operating from time to time. The higher the voltage level of the faulty branch, the greater the impact range. To effectively prevent accidents where important sensitive equipment stops operating due to "voltage sag" and "short-term interruption" faults caused by power supply side faults, a complete set of dual-power rapid switching devices has emerged. However, during the monitoring and operation of the complete set of dual-power rapid switching devices, a large amount of heat is often generated, and heat dissipation is required. For its heat dissipation, a fan is usually installed on the box body for air-cooled heat dissipation. However, due to air-cooled heat dissipation, it is affected by the external air temperature, resulting in unstable heat dissipation effect. Therefore, we propose a complete set of dual-power rapid switching devices. Content of the Utility Model

[0003] The utility model provides a complete set of dual-power rapid switching devices, which solves the problems raised in the above background technique.

[0004] To achieve the above objectives, the utility model is realized through the following technical solutions: A complete set of dual-power rapid switching devices includes a box body. A fan heat dissipation system is installed inside the box body. The two sides of the box body are of a multi-layer structure, and the fan heat dissipation system is installed on the inner two side walls of the outermost layer of the box body. A cavity is formed between the multi-layer structures on both sides of the box body. And a vortex-shaped cooling matrix for water cooling is installed at a position corresponding to the fan heat dissipation system on one side of the cavity. And a filter net for filtering is installed on the cooling matrix. Through holes are opened on the filter net. At the same time, an air inlet frame is detachably installed on the other side of the cavity. An inclined partition plate is connected to the air inlet frame through a pin.

[0005] Optionally, the middle of the air inlet frame is hollow, its partition plate is installed in the middle of the air inlet frame, its cavity can be communicated with the outside through the air inlet frame, and the space between the partition plates can fit and seal the air inlet frame.

[0006] Optionally, a liquid leakage port inclined outward is opened at the bottom end of the cavity, and the liquid leakage port is communicated with the outside.

[0007] Optionally, two connected waterways are opened inside the cooling matrix, a coolant storage cavity for storing coolant is opened inside the top end of the box body, the top end of the cooling matrix extends into the coolant storage cavity, and a circulation pump is fixedly connected to the top end of the cooling matrix.

[0008] Optionally, the water inlet of the circulation pump is communicated with one of the waterways, and the other waterway is communicated with the coolant storage cavity.

[0009] Optionally, the fan cooling system includes a fixed fan bracket, a fan, and a motor. A ventilation opening is opened on the box body, the fixed fan bracket is installed on the inner wall of the ventilation opening, a fan is installed on the fixed fan bracket, and a motor is fixedly connected to the outside of the fixed fan bracket. The output shaft of the motor is connected to the fan.

[0010] The present utility model has the following beneficial effects:

[0011] 1. For this dual-power fast-switching complete set of devices, under the action of the vortex-shaped structure of the cooling matrix, the contact area between the coolant and the air can be increased, thereby cooling the passing air. And under the action of the double waterways arranged in the cooling matrix, the contact area between the coolant and the air can be further increased, so that its cooling effect is better, thus improving its heat dissipation effect.

[0012] 2. For this dual-power fast-switching complete set of devices, due to the multi-layer structure on both sides of the box body, when cooling, rainwater will not directly enter the inside of the box body, the path of rainwater entry is extended, the obstacle for rainwater to enter the box body is increased, so that rainwater is difficult to enter the inside of the box body, thus improving its rain-proof effect.

[0013] 3. For this dual-power fast-switching complete set of devices, by rotating the partition plate to adjust the opening degree of the partition plate, air can enter smoothly. Under the action of the inclined partition plate, rainwater is not easy to enter the cavity, further improving its rain-proof effect. And when it rains heavily, rotate the partition plate so that the partition plate can seal the air inlet frame, thus effectively ensuring its rain-proof effect. Description of the Drawings

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 7, The dual-power fast-switching complete set of devices includes a box body 1. Inside the box body 1, a fan cooling system is installed. The two sides of the box body 1 are of a multi-layer structure, and the fan cooling system is installed on the inner walls of the two sides of the innermost layer of the box body 1, extending the path for rainwater to enter, increasing the obstruction for rainwater to enter the box body 1, and then making it difficult for rainwater to enter the box body 1, thus improving its rainproof effect. A cavity 5 is formed between the multi-layer structures on both sides of the box body 1, and a swirling cooling matrix 10 for water cooling is installed at a position corresponding to the fan cooling system on one side of the cavity 5, which can cool the air blown into the box body 1, thereby improving its heat dissipation effect. A filter screen 9 for filtering is installed on the cooling matrix 10 to prevent large impurities from entering the box body 1. Through holes are provided on the filter screen 9, and then the air can smoothly pass through the filter screen 9. At the same time, an air inlet frame 2 is detachably installed on the other side of the cavity 5. An inclined spacer 3 is connected to the air inlet frame 2 through a pin, forming a hinge structure with the pin as the rotation axis, so that the spacer 3 can rotate. Under the action of the inclined spacer 3, rainwater is not easily introduced into the cavity 5, further improving its rainproof effect.

[0025] Please refer to Figures 1 to 4 , The middle of the air inlet frame 2 is hollow. Its spacer 3 is installed in the middle of the air inlet frame 2. Its cavity 5 can be connected to the outside through the air inlet frame 2, and the spacers 3 can be attached to close the air inlet frame 2, thereby closing the air inlet frame 2 to prevent outside rainwater from entering, and providing rainproof protection during heavy rain, thus effectively improving its rainproof effect.

[0026] Please refer to Figures 1 to 5 , An inclined liquid leakage port 4 opening outward is provided at the bottom end of the cavity 5. The liquid leakage port 4 is connected to the outside, so that the water entering the cavity 5 can flow out smoothly, avoiding the accumulation of rainwater.

[0027] Please refer to Figures 1 to 7 , Two connected waterways are provided inside the cooling matrix 10. An internal coolant storage cavity 8 for storing coolant is provided at the top end of the box body 1. The top end of the cooling matrix 10 extends into the coolant storage cavity 8, and a circulation pump 7 is fixedly connected to the top end of the cooling matrix 10. Under the action of the circulation pump 7, the coolant can be smoothly transported into the cooling matrix 10, enabling the coolant to form a cycle inside the cooling matrix 10. With the design of the double waterways of the cooling matrix 10, the contact area between the coolant and the air can be further increased, and then its cooling effect is better, thus improving its heat dissipation effect.

[0028] Please refer to Figures 1 to 7 , The water inlet of the circulation pump 7 is connected to one of the waterways, and the other waterway is connected to the coolant storage cavity 8, so that the cooling matrix 10 can form a circulating path with the coolant storage cavity 8.

[0029] Please refer to Figures 1 to 8 , the fan cooling system includes a fixed fan bracket 11, a fan 12, and a motor 6. There is a ventilation opening on the box body 1, and the fixed fan bracket 11 is installed on the inner wall of the ventilation opening. The fan 12 is installed on the fixed fan bracket 11. The outer side of the fixed fan bracket 11 is fixedly connected to the motor 6, and the output shaft of the motor 6 is connected to the fan 12. Driven by the output shaft of the motor 6, the fan 12 can rotate, thereby performing air cooling on the inside of the box body 1.

[0030] In summary, for this dual-power fast-switching complete set of devices, when in use, driven by the output shaft of the motor 6, the fan 12 can rotate, and then form a wind blowing into the box body 1. The wind first enters the cavity 5 through between the spacer plates 3, and then passes through the cooling matrix 10. Under the action of the cooling matrix 10, the wind can be cooled to form cold air. And under the action of the filter screen 9, large impurities entering the cavity 5 can be intercepted. And under the action of the circulation pump 7, the cooling matrix 10 can continuously circulate the coolant, so that the coolant in the coolant storage cavity 8 can circulate with the cooling matrix 10.
