[0002] With the development of power system and the continuous improvement of user's requirement for power supply stability and reliability, as an indispensable part of distribution network, the importance of box type transformer substation is increasingly prominent. However, in the operation process of traditional box type transformer substation, due to the heat of internal electrical equipment, especially when working in high temperature environment, the problem of performance degradation, service life shortening and even failure caused by high temperature is prone to occur.

[0003] Most of the existing box type transformer substations adopt natural ventilation or simple forced ventilation to achieve heat dissipation. Natural ventilation depends on external environmental conditions such as wind speed and temperature difference, and it is difficult to ensure stable heat dissipation effect. The traditional forced ventilation scheme usually directly exhausts air through fan, lacks effective airflow guiding mechanism, resulting in uneven airflow distribution and low heat dissipation efficiency. In addition, some design schemes fail to fully utilize the internal space of transformer substation, so that the heat dissipation device occupies a large volume, affecting the layout and maintenance of other components.

DETAILED DESCRIPTION

[0042] The specific embodiments of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0043] The utility model relates to a kind of box-type substation with ventilation and heat dissipation effect, as shown in Figures 1 to 7 It includes:

[0044] Substation body 1 is independently fixedly arranged, provides a closed and controlled environment to protect internal electrical components from external environmental factors;

[0045] Mounting beam 2 is arranged in the top of the inner cavity of substation body 1, for installing heat dissipation equipment;

[0046] Guide mechanism 3 is rotatably arranged on mounting beam 2, for guiding airflow, so that air can flow more effectively;

[0047] Mounting shaft 4 is arranged on guide mechanism 3, and mounting shaft 4 coincides with the rotation axis of guide mechanism 3 and is rotatably mounted separately;

[0048] Mounting seat 5 is coaxially arranged on mounting shaft 4, and a plurality of heat dissipation fan blades 6 are arranged at equal intervals on mounting seat 5, for increasing the air flow rate inside substation body 1;

[0049] Driving mechanism 7 is arranged on mounting beam 2, for driving guide mechanism 3 and mounting shaft 4 to rotate;

[0050] The working principle of the device is as follows:

[0051] When the substation starts to work and generates heat, the driving mechanism 7 installed at the top of the inner cavity of the substation body 1 is activated, which drives the guide mechanism 3 and the mounting shaft 4 on the mounting beam 2 to rotate at the same time, and the multiple heat dissipation blades 6 arranged at equal angles on the mounting seat 5 rotate with the mounting shaft 4, further promoting the flow speed of the air inside the substation body 1. During the rotation of the guide mechanism 3, the airflow generated by the rotation of the multiple heat dissipation blades 6 can be guided; by setting the guide mechanism 3 in the substation body 1, and making the rotating axis of the mounting shaft 4 coincide with that of the guide mechanism 3 and being installed separately, the precise guidance and effective circulation of the airflow are realized, which greatly increases the heat dissipation area and improves the air flow speed, thereby significantly improving the heat dissipation efficiency. The driving mechanism 7 on the mounting beam 2 can stably drive the guide mechanism 3 and the mounting shaft 4 to rotate, ensuring the reliability and continuity of the heat dissipation system, and thus ensuring the stability of the overall work of the substation. The multiple heat dissipation blades 6 are arranged at equal angles on the mounting seat 5. This compact design not only ensures sufficient heat dissipation performance, but also effectively utilizes the limited space inside the substation, making the entire device more compact and reasonable.

[0052] In the prior art, the heat dissipation guide device usually adopts a simple fixed guide plate design to realize the basic airflow guiding function. However, these designs often have limitations, as they can only provide fixed airflow guiding paths and cannot be flexibly adjusted according to the actual heat load distribution and heat dissipation requirements inside the substation. To solve the above problems, the device designs a more optimal guide mechanism 3, as shown in Figures 3 to 7 , which includes:

[0053] The hollow shaft 31 is the core support of the entire guide mechanism, which is rotatably arranged in the inner hole of the mounting beam 2, and the mounting shaft 4 is rotatably arranged in the shaft cavity of the hollow shaft 31, so that the mounting shaft 4 and the guide mechanism 3 can move synchronously or asynchronously. Multiple extension beams 32 are arranged at equal intervals on the wall of the hollow shaft 31.

[0054] The mounting bracket 33 is arranged on the multiple extension beams 32, forming a stable platform, and multiple guide plates 34 are arranged at equal intervals on the mounting bracket 33. The guide plate 34 is a key element for airflow guidance, and the guide plate 34 is rotatably mounted on the mounting bracket 33. This design allows the guide plate to change the airflow direction according to actual needs.

[0055] The adjusting mechanism 35 is arranged on the mounting bracket 33 and is used to adjust the installation angle of the multiple guide plates 34.

[0056] The working principle of the guide mechanism 3 of the device is as follows:

[0057] When the drive mechanism 7 is started, it drives the hollow shaft 31 and the mounting bracket 33 on it to rotate together. At this time, the guide plate 34 will also rotate. However, since they can be adjusted at an angle independently of the mounting bracket, they can dynamically change the airflow direction according to different heat load requirements. At the same time, the mounting shaft 4 and the cooling fan blades 6 on it also rotate synchronously. Under their combined action, the air circulation speed inside the substation is enhanced, and the effective heat dissipation is promoted. In addition, in order to ensure the best working effect, the adjustment mechanism 35 can adjust the angle of the guide plate 34 to ensure that the ideal airflow guidance effect is achieved.

[0058] In existing technologies, the adjustment mechanism of heat dissipation guiding devices typically employs simple mechanical structures or electric devices to adjust the angle of the guide vanes. However, these existing technologies often suffer from problems such as complex operation, limited adjustment accuracy, and inability to simultaneously adjust the angles of multiple guide vanes, thus limiting the performance and flexibility of the heat dissipation guiding device. To address these issues, this device designs a superior adjustment mechanism 35, such as... Figure 4 As shown, it includes:

[0059] Two mounting bases 35a are located on the same side of the mounting bracket 33, and the mounting holes of the two mounting bases 35a are coaxially aligned.

[0060] The threaded rod 35b is rotatably mounted in the mounting holes of the two fixed seats 35a, and the rotation axis of the threaded rod 35b is perpendicular to the rotation axis of the multiple guide plates 34.

[0061] The rack 35c is slidably mounted on the mounting bracket 33, and the threaded rod 35b is installed in conjunction with the threaded hole of the rack 35c. When the threaded rod 35b rotates, the rack 35c will move linearly according to the direction and pitch of the thread.

[0062] Multiple transmission gears 35d are mounted on the guide plate 34, and each transmission gear 35d corresponds to a guide plate 34. The axis of the transmission gear 35d is installed to coincide with the rotation axis of the guide plate 34. The rack 35c meshes with the multiple transmission gears 35d, which ensures that each guide plate 34 can respond independently and synchronously to the movement of the rack 35c. The meshing connection between the transmission gears 35d and the rack 35c realizes the effective conversion from linear motion to rotational motion.

[0063] The working principle of the adjusting mechanism 35 of this device is as follows:

[0064] During operation, when the angle of the guide plate 34 needs to be adjusted, the threaded rod 35b can be manually rotated. As the threaded rod 35b rotates, the rack 35c moves linearly along the track on the mounting bracket 33 under the action of the thread. Since the rack 35c meshes with all the transmission gears 35d, this linear motion is converted into the rotational motion of each transmission gear 35d, which ultimately causes the angle of the guide plate 34 connected to it to change. In this way, the user can flexibly adjust the position of each guide plate 34 according to actual needs to adapt to different heat dissipation requirements or operating conditions. Through the cooperation of the precision-machined threaded rod 35b and the rack 35c, the angle of the guide plate 34 can be finely adjusted, thereby accurately controlling the airflow direction. All guide plates 34 can adjust their angles synchronously under the same command, ensuring the consistency and efficiency of airflow guidance.

[0065] In existing technologies, the drive mechanism of prefabricated substations typically employs a simple motor drive method, directly connecting the motor and the drive shaft to drive the heat dissipation equipment. However, these existing technologies often suffer from uneven distribution of driving force, inability to synchronously drive multiple components, and inability to flexibly adjust the driving force according to actual needs. These problems limit the performance and flexibility of the heat dissipation system, failing to meet the high requirements of this device for heat dissipation efficiency and precise airflow guidance. To solve these problems, this device designs a superior drive mechanism 7, such as... Figures 5 to 7 As shown, it includes:

[0066] Assembly frame 71 is mounted on mounting beam 2 and serves as a support platform for drive motor 72 and transmission mechanism 73;

[0067] The drive motor 72, mounted on the assembly frame 71, is the power core of the drive mechanism and is used to provide rotational power to both the mounting shaft 4 and the hollow shaft 31 simultaneously.

[0068] The transmission mechanism 73 is used to transmit the rotational power of the drive motor 72 to the mounting shaft 4 and the hollow shaft 31 respectively;

[0069] The working principle of the drive mechanism 7 of this device is as follows:

[0070] When the substation starts operating and generates heat, the control system starts the drive motor 72. The torque generated by the drive motor 72 is first transmitted to the hollow shaft 31, causing the guide mechanism 3 to start rotating. At the same time, the mounting shaft 4 rotates synchronously, causing the cooling fan blades 6 on the mounting base 5 to rotate as well. This design ensures that the mounting shaft 4 and the hollow shaft 31 can work together in a predetermined relationship, which not only achieves precise airflow guidance but also increases the airflow speed, thereby significantly improving the heat dissipation efficiency.

[0071] In existing technologies, the transmission mechanism of prefabricated substations typically uses simple direct connections or belt drives to drive the heat dissipation equipment. However, these existing technologies often suffer from uneven distribution of driving force, inability to synchronously drive multiple components, and inability to flexibly adjust the driving force according to actual needs. These problems limit the performance and flexibility of the heat dissipation system and cannot meet the high requirements of this device for heat dissipation efficiency and precise airflow guidance. To solve the above problems, this device designs a better transmission mechanism 73, such as... Figure 6 As shown, it includes:

[0072] The drive gear 73a is coaxially mounted at the output end of the drive motor 72;

[0073] Driven gear 73b is coaxially mounted on mounting shaft 4 and meshes with driving gear 73a;

[0074] The drive sprocket 73c is coaxially located at the output end of the drive motor 72, near the drive gear 73a but does not interfere with it;

[0075] Driven sprocket 73d is coaxially mounted on hollow shaft 31, and a chain 73e is meshed on driven sprocket 73c. ​​When drive motor 72 is running, chain 73e will drive driven sprocket 73d to rotate together.

[0076] The working principle of the transmission mechanism 73 of this device is as follows:

[0077] When the substation starts operating and generates heat, the control system starts the drive motor 72. The torque generated by the motor is first transmitted to the driven gear 73b through the driving gear 73a, causing the cooling fan blades 6 on the mounting shaft 4 and the mounting base 5 to rotate together, increasing the internal airflow speed. At the same time, the driving sprocket 73c also rotates with the drive motor 72, driving the driven sprocket 73d to rotate through the chain 73e, ultimately achieving synchronous rotation of the hollow shaft 31 and its guide mechanism 3. The gear and chain combination transmission method provides efficient kinetic energy conversion and reduces energy loss. By adjusting the ratio of gears and sprockets, the relative speed of the mounting shaft 4 and the hollow shaft 31 can be easily changed to adapt to different working conditions.

[0078] As a preferred option, such as Figure 3 As shown, the installation beam 2 is provided with an isolation element 73f, which is a sealed shell or cover, and the transmission mechanism 73 is located inside the isolation element 73f;

[0079] The isolator 73f provides a physical barrier, protecting the transmission mechanism 73 from external environmental factors and improving the stability and reliability of the system.

[0080] As a preferred option, such asFigure 2 and Figure 3 As shown, the substation body 1 is equipped with a baffle 8, and the guide mechanism 3 is located inside the baffle 8.

[0081] The barrier 8 provides a physical barrier to prevent personnel from coming into contact with the guide mechanism 3, thereby improving the protection of personnel and equipment.

[0082] As a preferred option, such as Figure 1 As shown, a rotating door 11 is provided at the outlet of the substation body 1, and a heat dissipation filter window 12 is provided on the rotating door 11.

[0083] The rotating door 11 provides a physical barrier to prevent personnel from direct contact with internal equipment, improving operational safety. The heat dissipation filter window 12 is designed to ensure sufficient ventilation while effectively filtering the incoming air, maintaining the cleanliness inside the substation.

[0084] The present invention relates to a prefabricated substation with ventilation and heat dissipation effects. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0085] 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.
