Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] This invention provides an industrial switching power supply, which improves the existing industrial power supply in high-end manufacturing, where industrial equipment needs to strictly ensure the normal operation of industrial power supplies. After working in a high-dust environment for a period of time, traditional industrial power supplies often have a large amount of dust adhering to their internal electronic components. Due to the large amount of dust accumulating on the electronic components, the heat dissipation effect of the electronic components becomes poor, which can easily cause fire hazards and even pose a risk of dust explosion.

[0041] The technical solution of this invention aims to improve the above-mentioned technical problems. The overall idea is as follows: By setting up the cooperation between the housing component 2, the dust-reducing component 4, and the flame-retardant component 3, when the power supply body 1 is working normally, the dust-reducing component 4 is activated and works in conjunction with the interaction of the housing component 2, thereby improving the dust-reducing effect of the dust-reducing component 4 on the power supply body 1, thus improving the service life of the components in the power supply body 1; when the power supply body 1 experiences a short circuit and generates electric sparks or other fire phenomena due to the accumulation of a lot of dust, smoke is generated in the power supply body 1. After the smoke is generated, the dust-reducing component 4 drives the flame-retardant component 3 to work, sealing the power supply body 1 in the housing component 2, blocking oxygen, and releasing carbon dioxide, thus extinguishing the open flame generated by the power supply body 1 in time, thereby reducing the safety hazard of dust explosion when the power supply body 1 is working;

[0042] To better understand the above technical solutions, the following will provide a detailed explanation of the above technical solutions in conjunction with the accompanying drawings and specific implementation methods;

[0043] This invention provides an industrial switching power supply, including a power supply body 1, and further comprising:

[0044] Housing assembly 2, which is disposed outside the power supply body 1;

[0045] Flame-retardant component 3, which is disposed inside the housing component 2, is used to extinguish any open flames that may be generated by the power supply body 1 in a timely manner;

[0046] Dust suppression component 4 is disposed above the power supply body 1 and located inside the housing component 2, and is used to provide power to the flame retardant component 3.

[0047] By adopting the above technical solution, during the normal operation of the power supply body 1, the dust reduction component 4 is activated. After the dust reduction component 4 is activated, in conjunction with the interaction of the housing component 2, the amount of dust adhering to the power supply body 1 inside the housing component 2 is greatly reduced, thereby improving the dust reduction effect of the dust reduction component 4 on the power supply body 1. As a result, if the amount of dust accumulated on the power supply body 1 is to reach the level that causes safety hazards such as short circuits in the components, it will take a longer time, thereby improving the service life of the components in the power supply body 1.

[0048] If the dust accumulated on the power supply body 1 reaches a certain amount, causing the heat dissipation effect of the power supply body 1 to deteriorate, resulting in the power supply body 1 becoming too hot, and thus causing a short circuit and electric sparks or other fire phenomena, smoke will be generated in the power supply body 1. After the smoke is generated, the dust suppression component 4 will drive the flame retardant component 3 to work, seal the power supply body 1 in the shell component 2, and release carbon dioxide to extinguish the open flame generated by the power supply body 1 in time, thereby reducing the safety hazard of dust explosion when the power supply body 1 is working.

[0049] Therefore, compared to existing high-end manufacturing, industrial equipment must strictly ensure the normal operation of industrial power supplies. After working in a high-dust environment for a period of time, traditional industrial power supplies often have a lot of dust adhering to their internal electronic components. Due to the large amount of dust accumulating on the electronic components, the heat dissipation effect of the electronic components becomes poor, which can easily cause fire hazards and thus pose a risk of dust explosion.

[0050] This invention, through the coordinated arrangement of the housing assembly 2, dust-reducing assembly 4, and flame-retardant assembly 3, improves the dust-reducing effect of the dust-reducing assembly 4 on the power supply body 1 during normal operation, thereby extending the service life of the components in the power supply body 1. When the power supply body 1 experiences a short circuit and fire due to excessive dust accumulation, smoke is generated in the power supply body 1. After the smoke is generated, the dust-reducing assembly 4 activates the flame-retardant assembly 3, sealing the power supply body 1 within the housing assembly 2, blocking oxygen, and releasing carbon dioxide to extinguish the open flame generated by the power supply body 1 in a timely manner, thus reducing the safety hazard of dust explosion during operation of the power supply body 1.

[0051] In one embodiment of the present invention, the housing assembly 2 includes:

[0052] Inner housing 21, which is wrapped around the outside of the power supply body 1;

[0053] The outer shell 22 is wrapped around the outer shell 21.

[0054] In one embodiment of the present invention, the dust removal component includes:

[0055] Motor 41 is fixedly connected to the outer upper surface of the outer shell 22. The rotating shaft of the motor 41 passes through the upper surface of the outer shell 22 and the inner shell 21 and extends downward into the interior of the inner shell 21. The rotating shaft of the motor 41 is rotatably connected to both the upper surface of the inner shell 21 and the upper surface of the outer shell 22.

[0056] Fan 42, the fan 42 is located above the power supply body 1, and the fan 42 is fixedly connected to one end of the rotating shaft of the motor 41 inside the inner housing 21;

[0057] A first through hole 43 is formed on the lower surface of the inner shell 21 and the outer shell 22;

[0058] In one embodiment of the present invention, the flame-retardant component 3 includes:

[0059] A receiving groove 31 is formed on the inner surface of the outer shell 22, and the receiving groove 31 is filled with carbon dioxide;

[0060] The sealing block 32 is fixedly connected to the outer surface of the inner shell 21 and slidably connected to the surface of the receiving groove 31.

[0061] Pneumatic telescopic rod 33, which is fixedly connected to the upper inner surface of the inner housing 21;

[0062] The slots 34 are evenly arranged in a ring on the rotating shaft of the motor 41 inside the inner housing 21;

[0063] Smoke alarm 35, which is fixedly connected to the bottom of the inner surface of the inner housing 21;

[0064] The control board 36 is located inside the housing assembly 2, and is electrically connected to the smoke alarm 35, the motor 41 and the pneumatic telescopic rod 33.

[0065] A flow port 37 is provided on the inner shell 21;

[0066] By adopting the above technical solution, when the power supply body 1 is working normally, the motor 41 is started. The rotating shaft of the motor 41 drives the fan 42 to rotate. The fan 42 generates airflow. Since the fan 42 is located above the power supply body 1, the airflow generated by the fan 42 is from top to bottom, which prevents most of the dust from entering the interior of the housing assembly 2 through the bottom of the housing assembly 2. As a result, the accumulation rate of dust adhering to the power supply body 1 is slowed down. Therefore, it takes longer for the amount of dust accumulated on the power supply body 1 to reach the level that causes safety hazards such as short circuits in the components, thereby improving the service life of the components in the power supply body 1. At the same time, due to the air cooling effect of the fan 42 and the No. 1 through hole 43 opened at the bottom of the inner housing 21 and the outer housing 22, the heat dissipation effect of the fan 42 on the power supply body 1 is guaranteed.

[0067] In addition, the motor 41 is an explosion-proof motor, and during the use of the motor 41, a dust filter is covered on its outer surface. Due to the dustproof effect of the dust filter, the possibility of dust adhering to the motor 41 is greatly reduced, thereby reducing the possibility of the motor 41 causing safety hazards due to a large amount of dust adhering to the motor 41.

[0068] When the amount of dust adhering to the electronic components in the power supply body 1 reaches a certain level, causing a short circuit in the power supply body 1 and generating a flame, the generated flame is accompanied by smoke. At this time, the fan 42 is still rotating, and the fan 42 still generates a downward airflow in the inner shell 21. Thus, when smoke is generated, the fan 42 can blow the smoke downward in the shortest time, that is, blow it towards the smoke alarm 35 located at the bottom of the inner shell 21. After the smoke alarm 35 senses the smoke, since the control board 36, the smoke alarm 35, the motor 41 and the pneumatic telescopic rod 33 are electrically connected, the smoke alarm 35 can sound an alarm and also feed back the smoke signal to the control board 36. After receiving the smoke signal, the control board 36 controls the pneumatic telescopic rod 33, which is electrically connected to it, to start through the circuit, and at the same time controls the motor 41 to shut down through the circuit.

[0069] When the pneumatic telescopic rod 33 is activated, its telescopic end extends toward the rotating shaft of the motor 41. Since the pneumatic telescopic rod 33 is fixedly connected to the upper surface of the inner housing 21, and multiple slots 34 are evenly arranged in a ring on the rotating shaft of the motor 41 inside the inner housing 21, even if the motor 41 is turned off at this time, the rotating shaft of the motor 41 will still rotate for a certain period of time due to its own inertia. During this period of rotation of the rotating shaft of the motor 41 due to its own inertia, the pneumatic telescopic rod 33 extends and inserts into the slot 4. At this time, the pneumatic telescopic rod 33 is connected to the rotating shaft of the motor 41 as one unit, and the pneumatic telescopic rod 33 is fixedly connected to the inner housing 21. Therefore, the rotating shaft of the motor 41, which continues to rotate due to inertia, drives the pneumatic telescopic rod 33 to rotate for a certain period of time. The rotation of the pneumatic telescopic rod 33 drives the inner housing 21, which is fixedly connected to it, to rotate.

[0070] On the one hand, since the inner shell 21 and the outer shell 22 both have a No. 1 through hole 43 at the bottom, and since the outer shell 22 is stationary when the inner shell 21 rotates, the No. 1 through hole 43 at the bottom of the inner shell 21 and the No. 1 through hole 43 at the bottom of the outer shell 22 are misaligned after the inner shell 21 rotates. As a result, the No. 1 through hole 43 on the inner shell 21 and the outer shell 22 are sealed due to the misalignment. Then the power supply body 1 is sealed in the shell assembly 2. Thus, when the power supply body 1 causes a fire hazard due to a short circuit, the combustion-supporting gas oxygen is blocked outside the shell assembly 2, thereby reducing the flame spread area and the possibility of continuous combustion, and improving the safety of the power supply body 1 after long-term use.

[0071] On the other hand, since the inner shell 21 rotates while the outer shell 22 remains stationary, and a receiving groove 31 is provided on the inner surface of the outer shell 22, containing carbon dioxide, and a sealing block 32 is fixedly connected to the outer surface of the inner shell 21, the sealing block 32 cooperates with the receiving groove 31. Therefore, when the inner shell 21 is not rotating, the sealing block 32 on the inner shell 21 cooperates with the receiving groove 31 on the outer shell 22 to seal the carbon dioxide in the receiving groove 31. When the inner shell 21 rotates, the sealing block 32 on the inner shell 21 moves away from the receiving groove 31, causing the receiving groove 31 to become sealed. At this time, it is in an open state, which allows carbon dioxide in the tank 31 to escape. Carbon dioxide is a flame-retardant gas. The escaped carbon dioxide fills the interlayer between the outer shell 22 and the inner shell 21. A flow port 37 is provided on the inner shell 21 between the sealing blocks 32. The carbon dioxide in the interlayer flows into the inner shell 21 through the flow port 37. The power supply body 1 is located in the inner shell 21, which further extinguishes the flame at the power supply body 1 in the inner shell 21, greatly reducing the possibility of dust explosion caused by flame spread and improving the safety of industrial production.

[0072] In addition, by fixing a rubber sealing sheet around the receiving groove 31, when the sealing block 32 rotates to cooperate with the receiving groove 31, the rubber sealing sheet is squeezed. The tension of the rubber sealing sheet after being squeezed, together with the presence of the sealing block 32, can achieve the sealing of the gas in the sealing groove 31, so as to avoid excessive leakage of gas in the sealing groove 31 and affect the normal use of the flame retardant component 3 in the later stage.

[0073] In one embodiment of the present invention, the end of the pneumatic telescopic rod 33 near the rotating shaft of the motor 41 is set in a hemispherical shape.

[0074] By adopting the above technical solution, when the telescopic end of the pneumatic telescopic rod 33 extends, since the end of the pneumatic telescopic rod 33 near the rotating shaft of the motor 41 is set as a hemispherical shape, the smoothness of the spherical surface allows the extended end of the pneumatic telescopic rod 33 to be more smoothly inserted into the slot 4 when it extends towards the rotating shaft of the motor 41. Furthermore, since the spherical surface is curved and the rotating shaft of the motor 41 is also curved, the contact point between the pneumatic telescopic rod and the rotating shaft of the motor 41 is a point, which can reduce the collision between the electric telescopic rod and the motor 41 when they rotate.

[0075] In one embodiment of the present invention, a support frame 5 is fixedly connected to the lower surface of the power supply body 1, and the end of the support frame 5 away from the power supply body 1 is fixedly connected to the lower surface of the inner surface of the outer shell 22.

[0076] In one embodiment of the present invention, an arc-shaped through groove 6 is provided on the lower surface of the inner shell 21, and the support frame 5 passes through the arc-shaped through groove 6.

[0077] By adopting the above technical solution, a support frame 5 is fixedly connected to the lower surface of the power supply body 1. The end of the support frame 5 away from the power supply body 1 is fixedly connected to the lower surface of the inner shell 22. On the one hand, the support frame 5 supports the power supply body 1, so that there is space between the lower surface of the power supply body 1 and the inner shell 21, which increases the heat dissipation of the bottom of the power supply body 1 and improves the heat dissipation effect of the fan 42 on the power supply body 1.

[0078] On the other hand, by setting the end of the support frame 5 away from the power supply body 1 to be fixedly connected to the lower inner surface of the outer shell 22, the support frame 5 is prevented from contacting the inner shell 21, which would cause the inner shell 21 to be subjected to a large gravity, resulting in the phenomenon that the inertial force of the rotating shaft of the motor 41 cannot drive the inner shell 21 to rotate. At the same time, an arc-shaped through groove 6 is set on the lower surface of the inner shell 21, and the support frame 5 passes through the arc-shaped through groove 6, so that when the inner shell 21 rotates, it will not be limited by the support frame 5 and will not be unable to rotate normally, thus ensuring the normal operation of the inner shell 21.

[0079] Furthermore, as the support frame 5 slides within the arc-shaped through groove 6, the inner housing 21 rotates due to the inertia of the motor 41's rotating shaft, while also being limited by the support frame 5 and the arc-shaped through groove 6. This prevents the inner housing 21 from rotating too much due to excessive inertia of the motor 41's rotating shaft, which would cause the sealing block 32 fixedly connected to the inner housing 21 to seal the receiving groove 31 again, preventing the carbon dioxide gas in the receiving groove 31 from escaping completely. Therefore, the arc-shaped through groove 6 can limit the inner housing 21, and after limiting the inner housing 21, it can brake the rotating shaft of the motor 41, ensuring the normal operation of the flame-retardant component 3.

[0080] The inner housing 21 is made of aluminum alloy, which ensures the hardness of the inner housing 21 while making it lightweight, thereby ensuring that the inertial force of the rotating shaft of the motor 41 can drive the inner housing 21 to rotate normally.

[0081] In one embodiment of the present invention, a second through hole 7 is provided on the upper surface of both the inner shell 21 and the outer shell 22.

[0082] By adopting the above technical solution, and by setting two through holes 7 on the upper surfaces of both the inner shell 21 and the outer shell 22, on the one hand, the ventilation of the two through holes 7 can ensure that the airflow on both sides of the fan 42 is unobstructed when the power supply body 1 is working normally, thus ensuring the heat dissipation effect of the fan 42 on the power supply body 1; on the other hand, when the power supply body 1 is working normally, the two through holes 7 on the upper surfaces of the inner shell 21 and the outer shell 22 are in an open and interconnected state. When the power supply body 1 is accidentally caught fire, the inner shell 21 rotates and the outer shell 22 is misaligned, and the two through holes 7 on the upper surfaces of the inner shell 21 and the outer shell 22 are also misaligned to achieve a seal on the power supply body 1.

[0083] In one embodiment of the present invention, the receiving slots 31 are interconnected, and an air inlet 8 is provided on the outer shell 22 at the uppermost receiving slot 31. An air inlet pipe 9 is fixedly connected to the surface of the air inlet 8. One end of the air inlet pipe 9 is located outside the outer shell 22, and the other end of the air inlet pipe 9 is connected to the receiving slot 31.

[0084] In one embodiment of the present invention, a rubber plug 10 is provided inside the air intake pipe 9;

[0085] By adopting the above technical solution, since the density of carbon dioxide is greater than that of air, carbon dioxide sinks in the air. When the carbon dioxide in the container 31 is released and needs to be replenished, the rubber plug 10 in the air intake pipe 9 is taken out for inflation. The carbon dioxide accumulates downward along the connecting channel of multiple container 31s, thus achieving inflation. After the carbon dioxide in the container 31 is replenished, the rubber plug 10 is inserted into the air intake pipe 9 to prevent air leakage and achieve reuse.

[0086] Working principle: When the power supply body 1 is working normally, the motor 41 is started. The rotating shaft of the motor 41 drives the fan 42 to rotate. The fan 42 generates airflow. Since the fan 42 is located above the power supply body 1, the airflow generated by the fan 42 is from top to bottom, which prevents most of the dust from entering the interior of the housing assembly 2 through the bottom of the housing assembly 2. As a result, the accumulation rate of dust adhering to the power supply body 1 is slowed down. Therefore, it takes longer for the amount of dust accumulated on the power supply body 1 to reach the level that causes short circuits or other safety hazards in the components, thereby improving the service life of the components in the power supply body 1. At the same time, due to the cooling effect of the fan 42 and the No. 1 through hole 43 opened at the bottom of the inner housing 21 and the outer housing 22, the heat dissipation effect of the fan 42 on the power supply body 1 is guaranteed.

[0087] When the amount of dust adhering to the electronic components in the power supply body 1 reaches a certain level, causing a short circuit in the power supply body 1 and generating a flame, the generated flame is accompanied by smoke. At this time, the fan 42 is still rotating, and the fan 42 still generates a downward airflow in the inner shell 21. Thus, when smoke is generated, the fan 42 can blow the smoke downward in the shortest time, that is, blow it towards the smoke alarm 35 located at the bottom of the inner shell 21. After the smoke alarm 35 senses the smoke, since the control board 36, the smoke alarm 35, the motor 41 and the pneumatic telescopic rod 33 are electrically connected, the smoke alarm 35 can sound an alarm and also feed back the smoke signal to the control board 36. After receiving the smoke signal, the control board 36 controls the pneumatic telescopic rod 33, which is electrically connected to it, to start through the circuit, and at the same time controls the motor 41 to shut down through the circuit.

[0088] When the pneumatic telescopic rod 33 is activated, its telescopic end extends toward the rotating shaft of the motor 41. Since the pneumatic telescopic rod 33 is fixedly connected to the upper surface of the inner housing 21, and multiple slots 34 are evenly arranged in a ring on the rotating shaft of the motor 41 inside the inner housing 21, even if the motor 41 is turned off at this time, the rotating shaft of the motor 41 will still rotate for a certain period of time due to its own inertia. During this period of rotation of the rotating shaft of the motor 41 due to its own inertia, the pneumatic telescopic rod 33 extends and inserts into the slot 4. At this time, the pneumatic telescopic rod 33 is connected to the rotating shaft of the motor 41 as one unit, and the pneumatic telescopic rod 33 is fixedly connected to the inner housing 21. Therefore, the rotating shaft of the motor 41, which continues to rotate due to inertia, drives the pneumatic telescopic rod 33 to rotate for a certain period of time. The rotation of the pneumatic telescopic rod 33 drives the inner housing 21, which is fixedly connected to it, to rotate.

[0089] On the one hand, since the inner shell 21 and the outer shell 22 both have a No. 1 through hole 43 at the bottom, and since the outer shell 22 is stationary when the inner shell 21 rotates, the No. 1 through hole 43 at the bottom of the inner shell 21 and the No. 1 through hole 43 at the bottom of the outer shell 22 are misaligned after the inner shell 21 rotates. As a result, the No. 1 through hole 43 on the inner shell 21 and the outer shell 22 are sealed due to the misalignment. Then the power supply body 1 is sealed in the shell assembly 2. Thus, when the power supply body 1 causes a fire hazard due to a short circuit, the combustion-supporting gas oxygen is blocked outside the shell assembly 2, thereby reducing the flame spread area and the possibility of continuous combustion, and improving the safety of the power supply body 1 after long-term use.

[0090] On the other hand, since the inner shell 21 rotates while the outer shell 22 remains stationary, and a receiving groove 31 is provided on the inner surface of the outer shell 22, containing carbon dioxide, and a sealing block 32 is fixedly connected to the outer surface of the inner shell 21, the sealing block 32 cooperates with the receiving groove 31. Therefore, when the inner shell 21 is not rotating, the sealing block 32 on the inner shell 21 cooperates with the receiving groove 31 on the outer shell 22 to seal the carbon dioxide in the receiving groove 31. When the inner shell 21 rotates, the sealing block 32 on the inner shell 21 moves away from the receiving groove 31, causing the receiving groove 31 to become sealed. At this time, it is in an open state, thus allowing the carbon dioxide in the tank 31 to escape. Carbon dioxide is a flame-retardant gas. The escaped carbon dioxide fills the interlayer between the outer shell 22 and the inner shell 21. A flow port 37 is provided on the inner shell 21 between the sealing blocks 32. The carbon dioxide in the interlayer flows into the inner shell 21 through the flow port 37. The power supply body 1 is located in the inner shell 21, thereby further extinguishing the flame at the power supply body 1 in the inner shell 21, greatly reducing the possibility of dust explosion caused by flame spread and improving the safety of industrial production.
