Description

Technical Field

[0001] The present invention relates to the technical field of explosion-proof electrical technology, and more particularly to a novel explosion-proof power distribution device. Background Art

[0002] An explosion-proof power distribution cabinet is an electrical device specifically designed for use in flammable and explosive environments, mainly used for safely distributing and controlling electrical energy. Its core feature is the explosion-proof function, which can effectively prevent the explosion of external explosive gases or dust caused by sparks or high temperatures generated by internal electrical components during operation.

[0003] However, the existing technology still has the following defects in specific use: 1. Compared with the existing explosion-proof power distribution devices, in order to ensure the explosion-proof performance, the structure is relatively enclosed, the air circulation is not smooth, and the natural convection heat dissipation method itself has low efficiency and is difficult to quickly remove a large amount of heat. Moreover, the size and quantity of the heat dissipation slots are usually restricted by the explosion-proof structure and cannot be increased arbitrarily, resulting in insufficient heat dissipation area. When operating at high load or in a high ambient temperature environment, the internal temperature will still be too high, which will affect the performance and lifespan of the electrical components. Furthermore, in order to achieve heat dissipation, the heat dissipation slots cannot be completely sealed, which provides an access channel for external impurities. In some harsh industrial environments, the air contains a large amount of dust and water vapor, and these impurities will enter the cabinet along with the air flow. At the same time, when the external environmental temperature changes greatly, the heat dissipation effect will also be affected. For example, in cold weather, excessive heat dissipation will cause condensation water to appear inside the cabinet, damaging the electrical components. Meanwhile, the distribution of electrical components in the cabinet is often uneven. Components with large power are concentrated in certain areas, generating concentrated heat, while the heat dissipation slots are generally evenly distributed on the side walls or the top and cannot effectively dissipate heat from the heat concentration areas. In addition, the wiring and other structures inside the cabinet will also affect the air flow, causing hot air to accumulate in certain areas and forming local high temperatures.

[0004] 2. Compared with the existing explosion-proof power distribution devices, the back panels are mostly designed with integral fixation. Once an internal component fails and needs to be repaired, due to the integral fixation of the back panel, maintenance personnel need to first remove a large number of electrical component connection lines on the front of the power distribution cabinet. During the process of removing the integral back panel, due to the narrow operating space, when maintenance personnel are screwing bolts and prying the back panel, the tools are extremely likely to touch the surrounding lines. In harsh environments such as coal mines, where the space is limited and the light is insufficient, the probability of misoperation increases greatly. With a little carelessness, the insulation layer of the line may be scratched, resulting in a short circuit of the line, not only causing new faults but also possibly generating sparks in an environment with extremely high explosion-proof requirements, leading to an explosion hazard. Moreover, when there are multiple potential fault points inside the power distribution cabinet, the overall fixed backplane makes it impossible for maintenance personnel to quickly inspect a specific area. For example, in the substation of urban rail transit, there are multiple functional modules in the power distribution cabinet. If one of the modules fails, due to the overall coverage of the backplane, it is impossible to directly view the internal situation of the corresponding module. It is necessary to remove the entire backplane and check one by one, which increases the difficulty of fault diagnosis and the repair time.

[0005] Therefore, in view of this, the present invention proposes a new type of explosion-proof power distribution device to make up for and improve the deficiencies of the existing technology. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides a new type of explosion-proof power distribution device to solve the technical problems raised in the above background technology.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: a new type of explosion-proof power distribution device, including a power distribution cabinet main body, a bearing backplane is installed inside the power distribution cabinet main body, electrical components are evenly installed on the surface of the bearing backplane, an electric control base is installed at the bottom of the power distribution cabinet main body, and a modular separation mechanism is arranged inside the power distribution cabinet main body. The modular separation mechanism is used to adjust the position of the electrical components according to the temperature change inside the power distribution cabinet main body.

[0008] Further, the modular separation mechanism includes a micro motor installed inside the power distribution cabinet main body. The outer wall of the output shaft end of the micro motor is fixedly connected with a threaded shaft. A nut sleeve is sleeved outside the threaded shaft. A driving backplane is fixedly connected to the surface of the nut sleeve. A limiting slide rail is installed on the surface of the driving backplane. The limiting slide rail is slidably connected with the electrical components.

[0009] Further, a temperature sensor is installed inside the power distribution cabinet main body. The temperature sensor is electrically connected with the micro motor. The micro motor is a swing motor whose output shaft end can rotate reciprocally.

[0010] Further, a ball screw structure is formed between the threaded shaft and the nut sleeve. In the initial state, the nut sleeve is located at the lowest end of the threaded shaft.

[0011] Further, the driving backplane is integrally in an I shape. Upper sliding grooves are penetrated on the surface of the upper half part of the driving backplane. Lower sliding grooves are penetrated on the surface of the lower half part of the driving backplane.

[0012] Further, connection blocks are installed inside both the upper sliding groove and the lower sliding groove. The connection blocks are fixedly connected with the electrical components. The driving backplane and the electrical components are slidably connected through the upper sliding groove, the lower sliding groove and the connection blocks.

[0013] Furthermore, a blocking frame is slidably connected to the surface of the driving back plate, and the blocking frame is cross-shaped as a whole, thereby dividing different electrical components into four different areas. Buffer springs are symmetrically installed on the surface of the blocking frame, and both ends of the buffer springs are fixedly connected to the blocking frame and the bearing back plate respectively.

[0014] Furthermore, a linkage heat dissipation mechanism is provided inside the main body of the distribution cabinet, and the linkage heat dissipation mechanism is used to dissipate heat inside the main body of the distribution cabinet synchronously with changes in the modular separation mechanism. The linkage heat dissipation mechanism includes a connecting plate symmetrically fixedly connected to the top of the driving back plate, and the upper surface of the connecting plate is evenly fixedly connected with a resistance shaft.

[0015] Furthermore, flat panels are evenly installed inside the power distribution cabinet body, and the inside of the flat panels are fixedly connected with horizontal axes, which are rotatably connected to the inner wall of the power distribution cabinet body, and both ends of the horizontal axes are sleeved with coil springs, and the two ends of the coil springs are respectively fixedly connected to the power distribution cabinet body and the flat panel.

[0016] Furthermore, a heat transfer pad is installed above the flat plate, a heat sink is installed above the heat transfer pad, a heat conducting plate is sleeved on the outside of the heat sink, and both the heat transfer pad and the heat conducting plate are made of boron nitride material.

[0017] Furthermore, the heat sink is composed of a plurality of sealed copper tubes filled with acetone liquid. The copper tubes in the heat sink are wide at the top and narrow at the bottom, and the lower section of the copper tubes is the evaporation section, and the upper section is the condensation section.

[0018] Compared with the prior art, the present invention has the following beneficial effects: (1) This device divides the inside of the power distribution cabinet into four module areas by introducing a cross-shaped barrier frame, thereby constructing a clear and orderly structural system. The electrical components in each module are initially installed close to the barrier frame, making full use of the space and making the layout compact and reasonable. At the same time, the barrier frame physically separates the modules and limits the scope of fault impact. When a short circuit or other fault occurs in a module, it can prevent the fault from spreading quickly to other modules, thereby improving the overall stability. Compared with the existing technology, the area design greatly simplifies the installation process. Installers can install electrical components in modules one by one, which makes the operation more organized and reduces the difficulty of installation. In addition, the advantages are more obvious during subsequent maintenance. The faulty module can be accurately located without large-scale disassembly of the entire cabinet, which reduces interference with the normally operating modules. In places with complex environments and high risk factors such as underground coal mines and petrochemicals, it can greatly shorten the maintenance time and reduce safety risks. What is particularly important is that when the temperature inside the cabinet rises, the micro motor will drive the electrical components to disperse. On the one hand, it increases the air circulation channels between the electrical components, allowing hot air to flow more smoothly inside the cabinet and speed up heat dissipation. On the other hand, after the components are dispersed, the contact area between each component and the surrounding cold air increases, and the heat dissipation efficiency is greatly improved, ensuring that the distribution device can maintain a suitable temperature even under long-term high-load operation, ensuring the stable performance of electrical components, reducing the risk of internal electric sparks, and enhancing the operating safety of the cabinet in flammable and explosive environments. Prevent explosion accidents caused by overheating.

[0019] (2) When the internal temperature of the equipment is normal, the flat panel remains in place, tightly isolating the inside of the cabinet from the external environment, forming a reliable barrier that can effectively block the entry of impurities such as dust, water vapor, and corrosive gases. In harsh industrial environments such as chemical and mining industries, it can prevent impurities from adhering to electrical components, reduce the risk of failures such as short circuits and corrosion, ensure the long-term safe and stable operation of the equipment, and reduce maintenance costs. On the contrary, when the internal temperature of the equipment is overloaded, the friction axis automatically triggers the heat dissipation mechanism, and the flat panel switches to an inclined state, quickly constructing a hot air flow channel, efficiently directing the internal hot air to the heat dissipation components, and achieving timely cooling, thereby avoiding abnormal pressure increase in the equipment due to high temperature, preventing the explosion-proof structure from being broken due to pressure, ensuring that the sealing and barrier properties of the cabinet are not damaged, and effectively resisting the intrusion of external flammable and explosive gases, ensuring safe operation; Compared with the traditional passive heat dissipation method, actively guiding the flow of hot air greatly improves the heat dissipation efficiency, effectively avoiding the performance degradation of electrical components caused by high temperature, and there is no need to open up a large area of ​​heat dissipation area or add complex pipelines. The heat dissipation and protection functions are achieved only by converting the state of the flat panel. The internal space of the cabinet is cleverly used to complete the dual tasks of heat dissipation and protection in a limited space. It is particularly suitable for places with high requirements for space layout, such as urban rail transit substations, ship power distribution systems and other usage scenarios; Among them, the device uses the interference shaft to realize the synchronous linkage of the modular separation mechanism and the heat dissipation mechanism, avoiding the complex independent control structure. This integrated design reduces the number of parts, simplifies the overall structure, reduces the production cost and assembly difficulty, and at the same time reduces the failure points caused by the large number of parts, and improves the overall operation stability of the equipment; Among them, the copper tube is designed to be wide at the top and narrow at the bottom. The larger radius of the evaporation section provides a larger space for the evaporation of acetone, which is conducive to the rapid evaporation of the liquid to form steam. The smaller radius of the condensation section speeds up the flow rate of the steam during the rising process, and the contact with the inner wall of the condensation section is more complete, thereby improving the condensation efficiency of the steam. At the same time, the condensed liquid can smoothly flow back to the evaporation section under the action of gravity, forming an efficient gas-liquid circulation and enhancing the heat transfer process.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention; It should be noted that the structures and working principles of the above-mentioned devices such as the main body 1 of the power distribution cabinet, the bearing backboard 11, the electrical components 12, and the electrical control base 13 belong to the prior art and will not be elaborated herein.

[0023] Example 1, please refer to Figure 1 - Figure 8As shown in the figure, a new type of explosion-proof power distribution device includes a power distribution cabinet main body 1. Inside the power distribution cabinet main body 1, a bearing backboard 11 is installed. On the surface of the bearing backboard 11, electrical components 12 are evenly installed. At the bottom of the power distribution cabinet main body 1, an electric control base 13 is installed. Inside the power distribution cabinet main body 1, a modular separation mechanism 2 is provided. The modular separation mechanism 2 is used to adjust the position of the electrical components 12 according to the temperature change inside the power distribution cabinet main body 1.

[0024] Please refer to Figure 1 - Figure 8 As shown in the figure, the modular separation mechanism 2 includes a micro motor 22 installed inside the power distribution cabinet main body 1. On the outer wall of the output shaft end of the micro motor 22, a threaded shaft 23 is fixedly connected. A nut sleeve 24 is sleeved outside the threaded shaft 23. On the surface of the nut sleeve 24, a driving backboard 25 is fixedly connected. On the surface of the driving backboard 25, a limit slide rail 29 is installed. The limit slide rail 29 is slidably connected with the electrical component 12. Inside the power distribution cabinet main body 1, a temperature sensor 21 is installed. The temperature sensor 21 is electrically connected with the micro motor 22. The micro motor 22 is a swing motor whose output shaft end can rotate reciprocally; It should be noted that a ball screw structure is formed between the threaded shaft 23 and the nut sleeve 24. In the initial state, the nut sleeve 24 is located at the lowest end of the threaded shaft 23. The driving backboard 25 is integrally in an I shape. Through holes are formed in the upper half surface of the driving backboard 25 to form an upper sliding groove 26, and through holes are formed in the lower half surface of the driving backboard 25 to form a lower sliding groove 27. Inside both the upper sliding groove 26 and the lower sliding groove 27, connecting blocks 28 are installed. The connecting blocks 28 are fixedly connected with the electrical components 12. The driving backboard 25 and the electrical components 12 are slidably connected through the upper sliding groove 26, the lower sliding groove 27, and the connecting blocks 28. A blocking frame 210 is slidably connected to the surface of the driving backboard 25. The blocking frame 210 is integrally in a cross shape, and thus different electrical components 12 are equally divided into four different areas. On the surface of the blocking frame 210, buffer springs 211 are symmetrically installed. Both ends of the buffer springs 211 are fixedly connected with the blocking frame 210 and the bearing backboard 11 respectively.

[0025] Specifically, when the power distribution cabinet main body 1 is in a normal operation state, the temperature sensor 21 monitors the temperature inside the power distribution cabinet main body 1 in real time. At this time, the micro motor 22 is not started, the nut sleeve 24 is located at the lowest end of the threaded shaft 23, the driving backboard 25 is in the initial position, and the electrical components 12 are centrally installed and close to the cross-shaped blocking frame 210, and are divided into four module areas by the blocking frame 210; When the temperature sensor 21 detects that the temperature inside the power distribution cabinet body 1 rises and reaches the set threshold, the temperature sensor 21 sends a signal to the micro motor 22, the micro motor 22 starts, and at the same time drives the fixedly connected threaded shaft 23 to rotate synchronously. Because a ball screw structure is formed between the threaded shaft 23 and the nut collar 24, when the threaded shaft 23 rotates, the nut collar 24 moves upward along the threaded shaft 23, and the driving back plate 25 fixedly connected to the surface of the nut collar 24 moves upward with the nut collar 24. During the movement of the driving back plate 25, the upper slide groove 26 on the upper surface and the lower slide groove 27 on the lower surface will squeeze the connecting block 28 upward during the movement, and then pass through the connecting block 28. The electrical components 12 are driven to move linearly outside the limiting slide rail 29. At this time, different electrical components 12 gradually move away from the blocking frame 210 and disperse to the surroundings. Since the inclination angles of the upper slide groove 26 and the lower slide groove 27 are different, the positions of the electrical components 12 located at the upper part of the power distribution cabinet body 1 and the electrical components 12 located at the lower part after movement are also different. In addition, the driving back plate 25 slides relative to the blocking frame 210 during the upward movement. Although the blocking frame 210 is basically fixed in position, the buffer spring 211 will be squeezed to a certain extent due to the movement of the driving back plate 25, which plays a buffering and stabilizing role, thereby preventing the driving back plate 25 from causing excessive impact on the blocking frame 210 and the entire structure; After the electrical components 12 are dispersed, more air circulation channels are formed between the electrical components 12, and the hot air can flow more smoothly inside the cabinet, accelerating the heat dissipation, thereby ensuring that the distribution device can maintain a suitable temperature under long-term high-load operation, ensuring the stable performance of the electrical components 12, and thus reducing the risk of internal electric sparks, and preventing explosion accidents caused by overheating. Later, when the internal temperature of the distribution cabinet body 1 drops to a normal range, the temperature sensor 21 sends a signal to the micro motor 22 again, and the micro motor 22 reverses. The movement process of the above components is reversed, and the nut collar 24 moves downward along the threaded shaft 23, driving the back plate 25 to drive the electrical components 12 to approach the barrier frame 210 again, and return to the initial centralized installation state, continuing to maintain the compact and reasonable layout of the distribution cabinet, and at the same time the barrier frame 210 and the buffer spring 211 also return to the initial stable state, and the entire device enters a new round of temperature monitoring and adjustment cycle.

[0026] Example 2, based on Example 1, please refer to Figure 1 - Figure 8 As shown, a linkage heat dissipation mechanism 3 is provided inside the power distribution cabinet body 1, and the linkage heat dissipation mechanism 3 is used to dissipate heat inside the power distribution cabinet body 1 synchronously according to the change of the modular separation mechanism 2. The linkage heat dissipation mechanism 3 includes a connecting plate 31 symmetrically fixedly connected to the top of the driving back plate 25, and the upper surface of the connecting plate 31 is evenly fixedly connected with a contact shaft 32; It should be noted that the inside of the power distribution cabinet body 1 is evenly installed with flat panels 33, the inside of the flat panels 33 is fixedly connected with a horizontal axis 34, the horizontal axis 34 is rotatably connected to the inner wall of the power distribution cabinet body 1, both ends of the horizontal axis 34 are sleeved with coil springs 35, the two ends of the coil spring 35 are respectively fixedly connected to the power distribution cabinet body 1 and the flat panel 33, a heat transfer pad 36 is installed above the flat panel 33, a heat sink 38 is installed above the heat transfer pad 36, a heat conducting plate 37 is sleeved on the outside of the heat sink 38, and the heat transfer pad 36 and the heat conducting plate 37 are both made of boron nitride material, the heat sink 38 is composed of a plurality of sealed copper tubes, the tubes are filled with acetone liquid, the copper tubes in the heat sink 38 are wide at the top and narrow at the bottom, and the lower section of the copper tube is the evaporation section, and the upper section is the condensation section.

[0027] Specifically, the boiling point of acetone is 56.53°C under standard atmospheric pressure, and it is generally believed that its boiling point range is approximately between 56°C and 57°C. Regarding the temperature range generated when the main body 1 of the power distribution cabinet is in operation, during normal operation, the internal temperature of the main body 1 of the explosion-proof power distribution cabinet is about 50°C to 80°C. When the internal temperature of the main body 1 of the explosion-proof power distribution cabinet exceeds 90°C, it can be considered that the temperature exceeds the range, and the performance of the electrical components 12 therein will be significantly affected, such as accelerated aging of insulating materials and drift of electronic component parameters. The temperature inside the power distribution cabinet body 1 is normal, the modular separation mechanism 2 is in the initial state, the driving back plate 25 is at a low position, and the abutment shaft 32 thereon does not act on the linkage heat dissipation mechanism 3. At this time, the flat plate 33 is kept horizontally in place under the action of the coil spring 35, and fits tightly inside the power distribution cabinet body 1, completely isolating the inside of the cabinet from the external environment, creating a good operating environment for the electrical components 12, and ensuring long-term stable operation of the equipment; When the temperature inside the power distribution cabinet body 1 rises and exceeds the set threshold, the various components in the modular separation mechanism 2 begin to operate in the above manner, wherein the connection plate 31 fixed above the driving back plate 25 will rise synchronously with it, thereby driving the evenly distributed friction shafts 32 on the upper surface of the connection plate 31 to move upward synchronously, and the upwardly moving friction shafts 32 gradually contact and squeeze the flat plate 33. Since the horizontal axis 34 is rotatably connected to the inner wall of the power distribution cabinet body 1, the flat plate 33 can rotate around the horizontal axis 34. With the continuous squeezing of the friction shaft 32, the external torque on the flat plate 33 gradually increases, overcoming the torsion of the coil spring 35. The coil spring 35 is gradually stretched to store elastic potential energy. When the external force applied by the friction shaft 32 is large enough, the flat plate 33 is converted from a horizontal state to an inclined state, and a hot air flow channel is constructed inside the power distribution cabinet body 1, so that the internal hot air can flow upward through these channels; The hot air rises through the channels formed by the flat plate 33 and first contacts the heat transfer pad 36. Since the heat transfer pad 36 is made of boron nitride material and has good thermal conductivity, it can quickly transfer the heat to the copper tube in the heat sink 38. The lower section of the copper tube is the evaporation section and is in the shape of wider at the top and narrower at the bottom. The larger radius provides a larger evaporation space for the acetone liquid. After absorbing heat, the acetone liquid quickly evaporates, changing from liquid state to gaseous state to form steam. The steam flows upward in the copper tube. Since the upper section of the copper tube is the condensation section and has a smaller radius, the flow rate of the steam accelerates during the upward movement, and the contact with the inner wall of the condensation section is more sufficient. At the same time, the heat conducting plate 37 sleeved outside the heat sink 38 is also made of boron nitride material, which can quickly transfer the heat to the external environment, making the temperature of the condensation section relatively low. In the condensation section with a lower temperature, the steam quickly releases heat when it meets the cold and re-condenses into liquid acetone. Due to the shape of the copper tube being wider at the top and narrower at the bottom, the condensed liquid acetone can smoothly flow back to the evaporation section under the action of gravity. In this way, the acetone liquid continuously undergoes evaporation and condensation cycles in the copper tube, continuously transferring the heat inside the main body 1 of the power distribution cabinet to the external environment, achieving efficient heat dissipation, timely reducing the temperature inside the main body 1 of the power distribution cabinet, avoiding abnormal increase in the pressure inside the equipment due to high temperature, ensuring that the sealing and barrier performance of the cabinet is not damaged, effectively resisting the intrusion of external flammable and explosive gases, and guaranteeing the operation safety; Finally, when the temperature inside the main body 1 of the power distribution cabinet drops to the normal range, the modular separation mechanism 2 operates in reverse. At this time, the coil spring 35 starts to release the stored elastic potential energy, driving the flat plate 33 to rotate reversely around the horizontal axis 34 and return to the horizontal original position, isolating the inside of the cabinet from the external environment again. At the same time, the intensity of the evaporation and condensation cycle of the acetone liquid in the heat sink 38 also weakens as the internal temperature decreases, and the whole device enters a new round of temperature monitoring and regulation cycle.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
