Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a busbar with a dustproof structure. Background Technology

[0002] A busbar trunking is a long cable box, a closed metal device made of copper and aluminum busbar columns. It is used to distribute a large amount of power to various components of a distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. It has the characteristics of compact structure and convenient and quick use. Furthermore, it improves its sealing performance by installing sealing gaskets inside, thereby preventing dust from entering.

[0003] A search revealed a busbar dustproof device disclosed in Chinese patent application number 202021004191.6. This patent belongs to the field of cable technology, specifically a busbar dustproof device, including a base plate with a vertical plate on top and a connecting plate at one end. The heat dissipation plate of this patent can initially filter external air entering the base plate, blocking impurities and large dust particles from reaching the outside of the heat dissipation plate. Simultaneously, the heat dissipation plate can dissipate heat generated during conductor operation, reducing the conductor's temperature, preventing heat loss, extending service life, and minimizing safety hazards, thus promoting long-term use of the equipment. By manually rotating the fixing pin, the fixing block is disengaged from the vertical plate. Then, by manually pulling out the push-pull handle, the heat dissipation plate is released from the first limiting groove, facilitating disassembly, cleaning, and replacement of the heat dissipation plate. The operation is simple, convenient, and highly practical.

[0004] While the aforementioned patent can initially filter external air entering the base plate, blocking impurities and large dust particles from the outside of the heat sink, and the heat sink can dissipate heat generated during conductor operation, thus reducing the heat and preventing heat loss, in actual use, due to the varying sizes of busbar trunking, some busbar trunkings are quite long. The patent uses a pull-out method to remove the heat sink and electrostatic adsorption plate, which results in the heat sink and electrostatic adsorption plate being too long, making them difficult to remove. This hinders cleaning and replacement by staff, thus reducing the practicality of the patent.

[0005] Therefore, the dustproof device for the busbar trunking in the aforementioned patent needs to be modified to effectively prevent the problem that when the heat dissipation plate and electrostatic adsorption plate are too long, it is difficult to pull them out and disassemble, which is not conducive to the cleaning and replacement by the staff.

[0010] As a preferred embodiment of this utility model, symmetrical limit grooves are provided on both sides of the rotating groove, and symmetrical limit blocks are fixedly connected to the surface of the column sleeve, with the limit blocks and limit grooves being slidably connected.

[0011] As a preferred embodiment of this invention, both ends of the blocking strip are fixedly connected to a stop block, and the stop block is slidably connected to the sliding frame.

[0014] 1. This utility model, through the arrangement of a busbar trunking body, a heat-absorbing plate, heat dissipation fins, a sealing frame, a vent, and a ventilation fan, utilizes the heat-absorbing plate to absorb the heat generated during conductor operation, which is then conducted to the heat dissipation fins for heat dissipation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5As shown, the present invention provides a busbar trunking with a dustproof structure, comprising a busbar trunking body 1, a heat-absorbing plate 2 fixedly connected to the top of the busbar trunking body 1, a heat dissipation fin 3 fixedly connected to the top of the heat-absorbing plate 2, a sealing frame 4 fixedly connected to the top of the busbar trunking body 1, and the bottom of the sealing frame 4 fitting against the heat dissipation fin 3, symmetrically provided ventilation openings 5 ​​on the top of the sealing frame 4, a ventilation fan 6 fixedly connected inside each of the two ventilation openings 5, symmetrically provided sliding grooves 7 on the surface of the sealing frame 4, sliding plates 8 slidably connected inside the sliding grooves 7, and a filter screen 9 and a dustproof screen 10 fixedly connected inside the two sliding plates 8 respectively.

[0024] refer to Figure 1 and Figure 4 The surface of the sealing frame 4 is symmetrically fixedly connected to the slide frame 11 about the slide groove 7, and the inside of the slide frame 11 is slidably connected to the blocking strip 12.

[0025] As a technical optimization of this utility model, the sliding frame 11 and the blocking strip 12 can block the movement trajectory of the skateboard 8, thereby preventing the skateboard 8 from sliding outward on its own and falling off.

[0026] refer to Figure 4 An extension block 13 is fixedly connected to the top of the upper sliding frame 11. A rotating groove 14 is opened on the top of the extension block 13. A bearing 15 is fixedly connected to the top of the rotating groove 14. A threaded column 16 is rotatably connected inside the bearing 15. A column sleeve 17 is fitted on the surface of the threaded column 16. A positioning groove 18 is opened on the top of the blocking strip 12, and the positioning groove 18 is engaged with the column sleeve 17.

[0027] As a technical optimization of this utility model, by setting the extension block 13, the rotating groove 14, the bearing 15, the threaded column 16, the column sleeve 17 and the positioning groove 18, the position of the slide plate 8 can be positioned to prevent it from sliding on its own during use.

[0028] refer to Figure 4 and Figure 5 The rotating groove 14 has symmetrically opened limit grooves 19 on both sides, and the surface of the column sleeve 17 is symmetrically fixedly connected to the limit block 20, and the limit block 20 is slidably connected to the limit groove 19.

[0029] As a technical optimization of this utility model, by setting the limiting groove 19 and the limiting block 20, the column sleeve 17 is prevented from rotating along with the rotation of the threaded column 16, thus ensuring that the column sleeve 17 performs linear movement.

[0030] refer to Figure 2 Both ends of the blocking strip 12 are fixedly connected to the blocking blocks 21, and the blocking blocks 21 are slidably connected to the sliding frame 11. The cross-sectional area of ​​the blocking blocks 21 is larger than the cross-sectional area of ​​the blocking strip 12.

[0031] As a technical optimization of this utility model, by setting the stop 21, the blocking strip 12 can be prevented from falling off and thus failing to block the slide plate 8, thereby improving the stability of the blocking strip 12 during use.

[0032] refer to Figure 2 and Figure 3 The diameter of filter screen 9 is larger than that of dustproof screen 10, and filter screen 9 is located above dustproof screen 10.

[0033] As a technical optimization of this utility model, by setting the mesh diameter of the filter screen 9 to be larger than that of the dustproof screen 10, a step-by-step filtration effect can be achieved, thereby improving the dust blocking effect.

[0034] The working principle and usage process of this utility model are as follows: When using this busbar trunking, first install the main body 1 of the busbar trunking in the designated position and connect it to the external connection equipment. When the main body 1 of the busbar trunking is used for transmission, the heat generated by the internal conductors will be absorbed by the heat absorption plate 2 and transferred to the heat dissipation fins 3 for heat dissipation. Then, ventilation is carried out by starting two ventilation fans 6. It should be noted that one of the two ventilation fans 6 should be set to intake and the other to exhaust. The airflow from the two ventilation fans 6 is then guided to form a more efficient airflow channel, which is conducive to heat dissipation of the heat dissipation fins 3 and reduces the operating temperature of the conductors. To prevent heat loss and extend service life, the filter screen 9 and dust filter 10 filter the air entering the heat sink fin 3 step by step, thus preventing dust from adhering to the heat absorption plate 2 and heat sink fin 3 and affecting their heat dissipation effect. When the filter screen 9 and dust filter 10 need to be cleaned or replaced, first rotate the threaded column 16 to move the column sleeve 17 upward until it leaves the positioning groove 18, then slide the blocking strip 12 to move it away from the sliding plate 8, and then slide the sliding plate 8 outward to clean or replace the filter screen 9 and dust filter 10. Then, the same operation is performed in reverse to quickly install and position them. The operation is simple.
