Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation equipment, and in particular to a heat dissipation structure for an intelligent modular box-type substation. Background Technology

[0002] With the rapid development of smart grid construction, modular prefabricated substations are increasingly widely used in distribution networks. However, due to their compact modular design and high power density operation characteristics, heat dissipation has become a key factor restricting equipment reliability and service life.

[0003] Traditional fixed cooling fans, installed in a single location, cannot achieve uniform air circulation within the substation, leading to prominent localized hotspots. Actual measurement data shows that, under the same cooling capacity, the internal temperature difference of a fixed fan system can reach 15-20℃, severely impacting the equipment's insulation performance. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a smart modular box-type substation heat dissipation structure with good heat dissipation effect and strong adaptability.

[0005] This utility model discloses an intelligent modular box-type substation heat dissipation structure, comprising:

[0006] The support frame is independently and fixedly installed at the heat dissipation holes of the substation.

[0007] The mounting shaft is rotatably mounted in the shaft hole of the support frame, and an extension is provided on the mounting shaft;

[0008] The connecting shaft is rotatably installed in the through hole of the extension, and the rotation axis of the connecting shaft is parallel to the rotation axis of the mounting shaft. A driven gear is coaxially fixedly installed on the connecting shaft.

[0009] The cooling fan is coaxially mounted on the connecting shaft, and the cooling fan rotates synchronously with the connecting shaft;

[0010] The drive shaft is installed inside the shaft cavity of the mounting shaft, and the drive shaft and the mounting shaft rotate independently. A drive gear is coaxially fixed on the drive shaft, and the drive gear and the driven gear are meshed together.

[0011] The drive mechanism, mounted on the support frame, is used to provide rotational power to the mounting shaft and the drive shaft respectively.

[0012] Furthermore, the drive mechanism includes:

[0013] The power shaft is rotatably mounted on the support frame, and one end is fixedly mounted on the drive motor. The drive motor is mounted on the support frame and is electrically connected to the control system on the substation.

[0014] The drive gear is coaxially mounted on the drive shaft and rotates synchronously with the drive shaft;

[0015] The transmission gear is coaxially fixedly mounted on the transmission shaft, and the transmission gear meshes with the power gear.

[0016] The control mechanism, mounted on the support frame, is used to provide rotational power to the mounting shaft.

[0017] Preferably, the control mechanism includes:

[0018] The servo motor is mounted on a support frame, and a worm gear is coaxially mounted on the output end of the servo motor. The servo motor is electrically connected to the control system.

[0019] The worm gear is coaxially mounted on the mounting shaft, and the worm and the worm gear are meshed together.

[0020] Furthermore, when a certain area of ​​the substation overheats, the cooling fan is driven to the overheated area by the control mechanism. The control mechanism stops rotating, and then the drive motor starts to drive the cooling fan to rotate and concentrate the heat dissipation of the overheated area.

[0021] When the substation overheats, the control mechanism continuously starts, driving the cooling fans to revolve to increase the heat dissipation area. At the same time, the drive motor drives the cooling fans to revolve while also rotating on its own axis.

[0022] Preferably, an auxiliary frame is provided on the support frame, and the worm gear is rotatably connected to the slot of the auxiliary frame.

[0023] Furthermore, a protective box is installed at one end of the support frame, and both the power gear and the transmission gear are located inside the protective box.

[0024] Preferably, the support frame is provided with elongated slots for installation.

[0025] Furthermore, an isolation net is installed at the other end of the support frame, and the cooling fan is located inside the isolation net.

[0026] A smart modular box-type substation heat dissipation structure was designed: a support frame is independently and fixedly installed at the substation's heat dissipation holes, serving as the foundation of the entire heat dissipation structure and providing a stable mounting platform for other components. The mounting shaft is rotatably mounted in the support frame's shaft hole, connecting to an extension component, allowing for the adjustment of the cooling fan's position. When the drive mechanism rotates the mounting shaft, the extension component and related components rotate accordingly, achieving the revolution of the cooling fan's heat dissipation position. This comprehensively covers different areas inside the substation, effectively preventing localized overheating. The connecting shaft is rotatably mounted in the extension component's through hole, parallel to the mounting shaft's rotation axis. A driven gear coaxially fixed on the connecting shaft, in conjunction with the driving gear on the transmission shaft, forms a highly efficient power transmission structure for heat dissipation. The fan is coaxially mounted on the connecting shaft and can rotate synchronously with the connecting shaft. When the drive mechanism and the transmission shaft work together, the cooling fan can achieve high-speed rotation through gear meshing, rapidly driving airflow and providing powerful air circulation inside the substation. This effectively reduces the temperature inside the substation and ensures the normal operation of electrical equipment. The transmission shaft is installed inside the mounting shaft cavity, and the two rotate independently, making the power transmission of the cooling structure more flexible. The drive mechanism provides rotational power to the mounting shaft and the transmission shaft separately or simultaneously, realizing multiple working modes of the cooling fan. It can flexibly adjust the cooling position and efficiently dissipate heat, comprehensively meeting the cooling needs of intelligent modular box-type substations under different operating conditions, and improving the stability and reliability of substation operation.

[0033] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0034] This utility model relates to a heat dissipation structure for an intelligent modular box-type substation, such as... Figures 1 to 5 As shown, it includes:

[0035] Support frame 1 is independently fixed and installed at the heat dissipation hole of the substation. Support frame 1 is the basic component of the entire heat dissipation structure.

[0036] Mounting shaft 2 is rotatably mounted in the shaft hole of support frame 1, and an extension 3 is provided on mounting shaft 2;

[0037] The connecting shaft 4 is rotatably installed in the through hole of the extension 3, and the rotation axis of the connecting shaft 4 is parallel to the rotation axis of the mounting shaft 2. A driven gear 5 is coaxially fixedly installed on the connecting shaft 4.

[0038] The cooling fan 6 is coaxially mounted on the connecting shaft 4 and rotates synchronously with the connecting shaft 4. The function of the cooling fan 6 is to effectively circulate air inside the substation and help dissipate heat and cool down.

[0039] The drive shaft 7 is installed inside the shaft cavity of the mounting shaft 2, and the drive shaft 7 and the mounting shaft 2 rotate independently. A drive gear 8 is coaxially fixed on the drive shaft 7, and the drive gear 8 is meshed with the driven gear 5.

[0040] The drive mechanism 9 is mounted on the support frame 1 and is used to provide rotational power to the mounting shaft 2 and the transmission shaft 7 respectively.

[0041] The support frame 1 is independently and fixedly installed at the heat dissipation hole of the substation, serving as the foundation of the entire heat dissipation structure and providing a stable installation platform for other components. The mounting shaft 2 is rotatably installed in the shaft hole of the support frame 1 and is connected to the extension 3, enabling the adjustment of the position of the cooling fan 6. When the drive mechanism 9 drives the mounting shaft 2 to rotate, the extension 3 and related components rotate accordingly, realizing the revolution of the cooling fan 6's heat dissipation position. This allows for comprehensive coverage of different areas inside the substation, effectively preventing local overheating. The connecting shaft 4 is rotatably installed in the through hole of the extension 3 and is parallel to the rotation axis of the mounting shaft 2. The driven gear 5, coaxially fixed on it, works with the driving gear 8 on the transmission shaft 7 to form an efficient power transmission structure. The cooling fan 6 is coaxially installed on the connecting shaft 4. On shaft 4, it can rotate synchronously with connecting shaft 4. When the drive mechanism 9 and the transmission shaft 7 cooperate to transmit power, the cooling fan 6 can achieve high-speed rotation through gear meshing, quickly promote air flow, and perform strong air circulation inside the substation, effectively reducing the temperature inside the substation and ensuring the normal operation of electrical equipment. The transmission shaft 7 is installed inside the shaft cavity of the mounting shaft 2 and the two rotate independently, making the power transmission of the heat dissipation structure more flexible. The drive mechanism 9 provides rotational power to the mounting shaft 2 and the transmission shaft 7 separately or simultaneously, realizing multiple working modes of the cooling fan 6. It can flexibly adjust the heat dissipation position and efficiently dissipate heat, comprehensively meeting the heat dissipation needs of the intelligent modular box-type substation under different operating conditions, and improving the stability and reliability of substation operation.

[0042] As a preferred option, such as Figures 2 to 5 As shown, the drive mechanism 9 includes:

[0043] The power shaft 91 is rotatably mounted on the support frame 1, and one end is fixedly mounted on the drive motor 92. The drive motor 92 is mounted on the support frame 1 and is electrically connected to the control system on the substation.

[0044] The power gear 93 is coaxially mounted on the power shaft 91, and the power gear 93 rotates synchronously with the power shaft 91;

[0045] The transmission gear 94 is coaxially fixedly mounted on the transmission shaft 7, and the transmission gear 94 is meshed with the power gear 93.

[0046] The control mechanism 95 is mounted on the support frame 1 and is used to provide rotational power to the mounting shaft 2.

[0047] The power shaft 91 is rotatably mounted on the support frame 1, with one end fixedly connected to the drive motor 92. The drive motor 92 is also mounted on the support frame 1 and electrically connected to the substation control system. This connection method ensures that the drive motor 92 can stably provide power to the entire drive mechanism 9, and the operation of the drive motor 92 can be flexibly adjusted by the control system according to the actual operating status of the substation to precisely match the heat dissipation requirements. The power gear 93 is coaxially mounted on the power shaft 91 and rotates synchronously, meshing with the transmission gear 94 coaxially fixed on the transmission shaft 7, forming an efficient power transmission path. When motor 92 starts, the power shaft 91 drives the power gear 93 to rotate, which in turn drives the transmission gear 94, causing the transmission shaft 7 to rotate rapidly. This ultimately achieves high-speed rotation of the cooling fan 6, providing powerful cooling for the interior of the substation. Meanwhile, the control mechanism 95, mounted on the support frame 1, is specifically designed to provide rotational power to the mounting shaft 2, enabling the cooling fan 6 to revolve and flexibly adjust its cooling position. This works in conjunction with the rotation of the cooling fan 6 to comprehensively cover all areas inside the substation, effectively preventing localized overheating and fully meeting the diverse needs of intelligent modular box-type substations for adjusting the cooling position and intensity under different operating conditions.

[0048] As a preferred option, such as Figures 2 to 5 As shown, the control mechanism 95 includes:

[0049] Servo motor 95a is mounted on support frame 1, and worm gear 95b is coaxially mounted on the output end of servo motor 95a. Servo motor 95a is electrically connected to control system. Auxiliary frame 95d is provided on support frame 1. Worm gear 95b is rotatably connected to the slot of auxiliary frame 95d.

[0050] Worm gear 95c is coaxially mounted on mounting shaft 2, and worm 95b is meshed with worm gear 95c;

[0051] The servo motor 95a, mounted on the support frame 1, is electrically connected to the control system. Based on the real-time operating data of the substation, it can accurately receive instructions from the control system and flexibly adjust its own speed and direction, thereby providing adaptive power for the position adjustment of the cooling fan 6. The worm gear 95b, coaxially mounted at its output end, rotates stably under the drive of the servo motor 95a and rotates in conjunction with the slot of the auxiliary frame 95d. This not only ensures the stability of the rotation of the worm gear 95b, but also further supports the power transmission structure. The worm gear 95b meshes with the worm wheel 95c, which is coaxially mounted on the mounting shaft 2. Utilizing the characteristics of worm gear transmission, a large transmission ratio can be achieved, outputting a large torque at a low speed, so that the mounting shaft 2 can rotate smoothly and accurately, thereby driving the extension 3 and the cooling fan 6 to revolve and flexibly adjust the heat dissipation position, ensuring that the cooling fan 6 evenly covers different areas inside the substation.

[0052] As a preferred option, such as Figures 2 to 5 As shown, when a certain part of the substation overheats, the cooling fan 6 is driven to rotate to the overheated area by the control mechanism 95. The control mechanism 95 stops rotating, and then the drive motor 92 starts to drive the cooling fan 6 to rotate and concentrate on cooling the overheated area.

[0053] When the substation is overheated, the control mechanism 95 is continuously activated, driving the cooling fan 6 to revolve to increase the heat dissipation area. At the same time, the drive motor 92 drives the cooling fan 6 to revolve while rotating on its own axis.

[0054] When a localized overheating occurs in the substation, the control mechanism 95 responds quickly, driving the cooling fan 6 to precisely rotate to the overheated area. Utilizing the precise control of the servo motor 95a and the accuracy of the worm gear transmission, the position of the cooling fan 6 is quickly and stably adjusted. Then, the control mechanism 95 stops rotating, locking the cooling fan 6 in the optimal heat dissipation position. Immediately afterwards, the drive motor 92 starts, causing the cooling fan 6 to rotate at high speed. With its powerful airflow capability, it concentrates and strongly dissipates heat from the overheated area, rapidly reducing the temperature of that localized area. This effectively prevents electrical equipment failures caused by localized overheating and ensures the stable operation of critical components in the substation. When the substation overheats, the control mechanism 95 continues to operate, driving the cooling fan 6 to revolve and continuously expand the heat dissipation coverage area, enabling the cooling fan 6 to traverse all areas inside the substation and ensure comprehensive heat dissipation without any dead corners. At the same time, the drive motor 92 works synchronously, driving the cooling fan 6 to rotate at high speed during the revolving process. Under the dual action, the comprehensive air circulation and heat exchange inside the substation are accelerated, significantly enhancing the heat dissipation effect, rapidly reducing the temperature inside the entire substation, and creating a suitable operating environment for electrical equipment.

[0055] As a preferred option, such as Figure 2 As shown, a protective box 10 is installed at one end of the support frame 1, and the power gear 93 and the transmission gear 94 are both located inside the protective box 10;

[0056] The protective box 10 can effectively block external dust, moisture and other impurities, preventing them from entering the meshing area of ​​the power gear 93 and the transmission gear 94, reducing gear wear caused by impurities, extending gear service life, and preventing damage to the gears from accidental collisions, thus avoiding drive mechanism 9 failure caused by gear damage.

[0057] As a preferred option, such as Figures 1 to 3 As shown, the support frame 1 is provided with elongated slots for installation;

[0058] When installing the heat dissipation structure to the heat dissipation hole of the substation, the long slot allows the installer to flexibly adjust the installation position of the support frame 1 within a certain range without the need to precisely locate each installation point. Even if there are certain dimensional tolerances in the surrounding structure of the substation heat dissipation hole or the installation space is limited, the support frame 1 can be easily installed through the long slot, effectively saving installation time and labor costs.

[0059] As a preferred option, such as Figure 1 As shown, an isolation net 11 is installed at the other end of the support frame 1, and the cooling fan 6 is located inside the isolation net 11;

[0060] While ensuring the normal operation of the cooling fan 6, the isolation net 11 provides safety for personnel operation, preventing personnel from accidentally touching the high-speed rotating cooling fan 6, preventing accidents, and improving the overall safety of the heat dissipation structure.

[0061] The present invention relates to an intelligent modular box-type substation heat dissipation structure. Its installation method, connection method, or setting method are all common mechanical methods. As long as it can achieve its beneficial effect, it can be implemented.

[0062] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
