[0002] Busbar trunking is a closed metal device made of copper and aluminum busbar columns. It is used to distribute large amounts of power to various components of a distributed system and has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] For example, the patent entitled "A Compact Busbar with Built-in Temperature Control Device" (patent application number: CN202321112773.X) discloses a compact busbar with built-in temperature control device. Through the cooperation between the filter screen, the fan, the air supply pipe and the connecting pipe, it is easy for external air to enter the ventilation pipe through the filter and be discharged from the ventilation port, thereby facilitating uniform heat dissipation for each busbar. At the same time, through the cooperation between the temperature sensor, the controller and the fan, it is easy to control the opening and closing of the fan according to the temperature inside the bottom shell, thereby facilitating timely heat dissipation inside the bottom shell. However, impurities in the external air are prone to accumulate on the lower surface of the filter screen, causing filter screen blockage and affecting heat dissipation efficiency.

[0004] Therefore, it is necessary to propose an intelligent temperature control structure for busbar trunking to solve the above problems. Utility Model Content

[0010] Preferably, a solenoid valve is fixedly installed on the connecting pipe, and a temperature sensor is provided between two adjacent busbars, with the temperature sensor cooperating with the corresponding solenoid valve.

[0011] Preferably, a second square groove is formed on the upper surface of the top of the housing, and a first square groove is formed at the bottom of the second square groove. The length and width of the second square groove are greater than the length and width of the first square groove, respectively. A rotating rod is fixedly connected inside the second square groove, and a cover plate is rotatably connected to the rotating rod.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by setting up a filter screen and scraper, etc., allows the filter screen to filter impurities in the outside air, and during the rotation of the shaft, it will drive the scraper to push and scrape the lower surface of the filter screen, so as to avoid the filter screen from becoming clogged and improve the efficiency of ventilation and heat dissipation.

[0014] 2. By setting up structures such as air supply ducts and air vents, targeted air supply and heat dissipation can be achieved, improving heat dissipation efficiency and achieving intelligent control; at the same time, compared with the overall air supply method, it can avoid the dispersion of air force and improve the effect of air force.

[0015] 3. When gas is supplied to the busbar through the air supply pipe and air hole, the cover plate will flip upward with the rotating rod as the axis, opening the first square groove and the second square groove to facilitate gas discharge and realize gas circulation inside the shell; after the heat dissipation is completed and the motor stops running, the cover plate will flip downward and reset due to its own weight, closing the first square groove to prevent impurities from entering the interior of the shell.

[0022] This utility model provides, for example Figures 1-5 The diagram shows an intelligent temperature control structure for a busbar trunking, which includes a housing 1, on which busbars 2 are provided, and multiple busbars 2 are provided.

[0023] Considering that the heat generation of each busbar 2 is different during use, in order to improve the heat dissipation efficiency, an air supply pipe 3 is provided between two adjacent busbars 2, and the air supply pipe 3 is distributed along the length of the shell 1. The top of the air supply pipe 3 is provided with air holes 4, and multiple air holes 4 are provided.

[0024] A horizontal pipe 5 is fixedly connected to the upper surface of the bottom of the housing 1, and a connecting pipe 6 is fixedly connected to the bottom end of the air supply pipe 3. The connecting pipe 6 is fixedly connected to the horizontal pipe 5, and the air supply pipe 3 is connected to the horizontal pipe 5 through the connecting pipe 6. The air supply pipe 3, the connecting pipe 6, and other structures are all made of insulating material.

[0025] A solenoid valve 7 is fixedly installed on the connecting pipe 6, and a temperature sensor 16 is installed between each of the two adjacent busbars 2. The temperature sensor 16 is matched with the corresponding solenoid valve 7.

[0026] Specifically, a controller can be configured to connect the corresponding solenoid valve 7 and temperature sensor 16. When temperature sensor 16 detects that the temperature in the corresponding area exceeds a set threshold, this information is transmitted to the controller. The controller then controls the solenoid valve 7 to open, thereby supplying gas to the busbar 2 through the corresponding air supply pipe 3 and air vent 4. This achieves targeted air supply and heat dissipation, improves heat dissipation efficiency, and achieves intelligent control. Furthermore, compared to overall air supply, it avoids airflow dispersion and improves the effectiveness of airflow. The controller and its control principle are common existing technologies and will not be elaborated upon here.

[0027] The bottom of the housing 1 is provided with an air supply assembly for supplying gas to the air supply duct 3. The air supply assembly includes an outer cylinder 8, a filter screen 9, a rotating shaft 10, a fan 11, and a scraper 12.

The filter screen 9 is fixedly connected to the bottom of the outer cylinder 8. The rotating shaft 10 is rotatably mounted on the filter screen 9. The fan 11 is fixedly connected to the rotating shaft 10 and is located inside the outer cylinder 8. The scraper 12 is fixedly connected to the bottom of the rotating shaft 10 and is attached to the lower surface of the filter screen 9.

[0028] A bracket 13 is fixedly connected to the inner wall of the outer cylinder 8, and a rotating shaft 10 is rotatably connected to the bracket 13. A motor 14 is fixedly connected to the top of the bracket 13, and the rotating shaft 10 is fixedly connected to the drive shaft of the motor 14.

[0029] In actual use, the motor 14 drives the fan 11 to rotate through the shaft 10, so that the external air enters the interior of the horizontal tube 5 from the outer cylinder 8 and is delivered to the corresponding connecting pipe 6, and is sprayed out to the busbar 2 through the air hole 4 for heat dissipation.

[0030] By setting up structures such as filter screen 9 and scraper 12, filter screen 9 can filter impurities in the outside air. During the rotation of shaft 10, it will drive scraper 12 to push and scrape the lower surface of filter screen 9, so as to avoid clogging of filter screen 9 and improve ventilation and heat dissipation efficiency.

[0031] A second square groove 18 is provided on the upper surface of the top of the housing 1, and a first square groove 17 is provided at the bottom of the second square groove 18. The length and width of the second square groove 18 are greater than the length and width of the first square groove 17, respectively. A rotating rod 15 is fixedly connected inside the second square groove 18, and a cover plate 19 is rotatably connected to the rotating rod 15.

[0032] When gas is supplied to the busbar 2 through the air supply pipe 3 and the air hole 4, the cover plate 19 will flip upward with the rotating rod 15 as the axis, and the first square groove 17 and the second square groove 18 will open to facilitate the gas discharge and realize the gas flow inside the housing 1. After the heat dissipation is completed and the motor 14 stops running, the cover plate 19 will flip downward and reset due to its own gravity, closing the first square groove 17 to prevent impurities from entering the interior of the housing 1.
