Description

Technical Field

[0001] This utility model relates to the technical field of outdoor terminal boxes for substations, specifically a dustproof and heat dissipation structure for outdoor terminal boxes in substations. Background Technology

[0002] For terminal boxes installed outdoors in substations, the hot and humid weather in summer causes a large temperature difference between the inside of the terminal box and the environment. Uneven heat dissipation of the terminal box can easily lead to internal metal corrosion, poor secondary terminal connection, overheating and arcing. In the existing technology, heat dissipation is mostly achieved by opening heat dissipation vents. However, this method is not very effective and can easily cause dust to accumulate on the wires inside the terminal box, which is even more detrimental to heat dissipation and will affect the use of the terminal box and shorten its service life.

[0003] A smart heat dissipation device for a substation terminal box is disclosed in CN205693204U. It includes a terminal box body, with a temperature and humidity sensor installed on the top plate inside the body. Exhaust fans are installed on the upper part of both side plates of the terminal box body, and exhaust pipes are bolted to the side plates corresponding to the exhaust fans. A base is connected to the lower end of the terminal box body. Ventilation windows are symmetrically arranged on the front and rear panels of the base. C-shaped tracks are symmetrically arranged along the length of the upper and lower plates inside the base. Dustproof nets are installed between the C-shaped tracks, and a handle is provided at one end of the dustproof net. The upper plate between the C-shaped tracks inside the base has through holes and ventilation holes that communicate with the terminal box body. This device has the advantages of simple structure, good heat dissipation, convenient installation, rain and dust protection, and automatic heat dissipation and dehumidification based on temperature and humidity conditions.

[0004] In current substation terminal box heat dissipation structure designs, a combination of ventilation and heat dissipation is typically used to ensure effective ventilation and heat dissipation inside the terminal box. In the aforementioned intelligent heat dissipation device for substation terminal boxes, the designer aims to achieve heat dissipation while ensuring airflow by setting up dustproof nets and designing interconnected holes. However, to ensure unobstructed airflow, the dustproof nets are designed with a porous structure. While this porous structure, along with the design of other ventilation holes, ensures heat dissipation inside the box, it also brings problems. Due to the presence of these holes, fine dust particles can enter the equipment with the airflow. Therefore, although the heat dissipation function of the terminal box is achieved, its overall performance in dust prevention and heat dissipation is not optimal.

[0005] Therefore, those skilled in the art have provided a dustproof and heat dissipation structure for outdoor terminal boxes in substations to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to provide a dustproof and heat dissipation structure for outdoor terminal boxes in substations, so as to solve the problem mentioned in the background art that the comprehensive performance of existing outdoor terminal boxes in substations in terms of dustproofing and heat dissipation is not optimal.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A dustproof and heat dissipation structure for an outdoor terminal box in a substation includes: a terminal box body, a heat dissipation window installed on the side of the terminal box body, a heat dissipation fan fitted on the top of the terminal box body, a ventilation window below the heat dissipation fan, a protective cover installed on the top outer side of the heat dissipation fan, a mounting seat ring provided on the bottom outer edge of the heat dissipation fan, a flange ring fixedly provided on the top edge of the ventilation window, a ventilation pipe installed in the middle of the interior of the ventilation window, a curved groove connected to the lower outer side of the ventilation pipe, a retainer fixedly installed inside the curved groove, a filter screen for dust filtration fitted inside the retainer, an air outlet provided at the end of the curved groove away from the ventilation pipe, and the curved groove communicating with the interior of the terminal box body through the air outlet.

[0008] As a further improvement of this utility model: the ventilation window extends from the top of the terminal box body to the inner top of the terminal box body, and the bottom of the cooling fan is provided with a hopper pipe.

[0009] As a further improvement of this utility model: the mounting sleeve and the cooling fan are fixedly connected, and the inner wall of the mounting sleeve has a threaded structure.

[0010] As a further embodiment of this utility model: the outer wall of the mounting sleeve ring and the flange ring are connected by a thread, and the cooling fan is connected to the ventilation window through the threaded connection structure between the mounting sleeve ring and the flange ring.

[0011] As a further embodiment of this utility model: the external structure of the curved groove is curved, and the curved groove is distributed in a cross shape with respect to the symmetrical center line of the ventilation pipe.

[0012] As a further embodiment of this utility model: the inlet end of the curved groove is connected to the lower end of the ventilation pipe, and the curved groove is connected to the cooling fan through the ventilation pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. A cooling fan is embedded in the top of the terminal box body. An integrated mounting bracket is provided on the bottom outer edge of the cooling fan. A ventilation window is provided below the cooling fan. The ventilation window penetrates the top of the terminal box body and is installed on the top of the inner wall of the terminal box. The air from the cooling fan enters the interior of the ventilation window through the ventilation pipe. The lower end of the ventilation pipe has a hollow structure. Air will enter the curved groove from the ventilation pipe. The curved groove is used to transport the air. The curved structure of the curved groove can effectively prevent dust from directly entering the interior of the terminal box body. In this way, when cooling the interior of the terminal box body, dust is indirectly intercepted. The use of multiple sets of curved grooves with curved structures extends the transport path and complicates the transport path. At the same time, a filter screen is embedded in the curved groove. The filter screen works with the curved groove to filter and intercept the dust carried in the air, further improving the overall dustproof and heat dissipation performance. 2. The mounting sleeve ring and flange ring are connected by threads. The cooling fan is connected to the top of the ventilation window using the threaded connection. This facilitates the disassembly of the cooling fan. After removing the cooling fan from the top of the ventilation window, the inside of the ventilation window is exposed. The filter screen can be pulled out for cleaning and replacement using the interlocking structure between the mounting bracket and the filter screen. This achieves dust prevention and heat dissipation while preventing internal blockage, further improving the overall performance of dust prevention and heat dissipation. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-5 This utility model provides a dustproof and heat dissipation structure for an outdoor terminal box in a substation, comprising: a terminal box body 1, a heat dissipation window 2 installed on the side of the terminal box body 1, a heat dissipation fan 3 fitted on the top of the terminal box body 1, a ventilation window 6 provided below the heat dissipation fan 3, a protective cover 4 installed on the outer side of the top of the heat dissipation fan 3, a mounting seat ring 5 provided on the outer edge of the bottom of the heat dissipation fan 3, and a flange ring 7 fixedly provided along the top edge of the ventilation window 6. The ventilation window 6 extends from the top of the terminal box body 1 to the inner top of the terminal box body 1. A funnel pipe 13 is provided at the bottom of the heat dissipation fan 3. The mounting seat ring 5 and the heat dissipation fan 3 are fixedly connected, and the inner wall of the mounting seat ring 5 has a threaded structure. The outer wall of the mounting seat ring 5 and the flange ring 7 form a threaded connection, and the heat dissipation fan 3 is connected to the ventilation window 6 through the threaded connection structure between the mounting seat ring 5 and the flange ring 7. Specifically, a mounting sleeve 5 is integrally set on the bottom edge of the cooling fan 3. The mounting sleeve 5 and the flange ring 7 set on the top of the ventilation window 6 are threaded together, thus realizing the stable installation of the cooling fan 3 on the top position of the ventilation window 6. This threaded connection not only ensures the reliability of the installation, but also provides great convenience, as it allows users to easily disassemble the cooling fan 3 to facilitate necessary maintenance and cleaning of the inside of the ventilation window 6. The ventilation window 6 is designed to penetrate through the top of the terminal box body 1 and is installed at the inner top position of the terminal box body 1. This design ensures effective communication between the ventilation window 6 and the cooling fan 3. Through this communication, the cooling fan 3 can effectively blow air to cool the inside of the terminal box body 1, ensuring that the equipment operates under suitable temperature conditions. The air is discharged from the heat dissipation windows 2 on both sides of the terminal box body 1. This design not only improves the heat dissipation efficiency, but also effectively prevents dust and other small particles from entering the inside of the terminal box through the double-layer mesh structure covering the inner wall of the heat dissipation window 2, thereby protecting the internal electronic components from contamination.

[0022] Ventilation duct 8 is installed in the middle of the ventilation window 6, and curved groove 9 is connected to the lower outer side of ventilation duct 8. A bracket 11 is fixedly installed inside the curved groove 9, and a filter screen 12 for dust filtration is fitted inside the bracket 11. An air outlet 10 is provided at the end of the curved groove 9 away from ventilation duct 8, and the curved groove 9 is interconnected with the interior of terminal box body 1 through the air outlet 10. The external structure of the curved groove 9 is curved, and the curved groove 9 is distributed in a cross shape about the symmetrical center line of ventilation duct 8. The inlet end of the curved groove 9 is interconnected with the lower end of ventilation duct 8, and the curved groove 9 is interconnected with cooling fan 3 through ventilation duct 8. Specifically, the internal structure of the cooling fan 3 is designed in the shape of a bucket, with the bottom opening pipe 13 smoothly connected to the upper end of the ventilation pipe 8. This design ensures that the air generated by the cooling fan 3 can effectively enter through the ventilation pipe 8 and flow along a specific path. The lower end of the ventilation window 6 and the inlet end of the curved groove 9 are also designed to be interconnected, so that the air can smoothly enter the interior of the curved groove 9 from the ventilation pipe 8. The curved structure of the curved groove 9 not only helps to extend the airflow path, but also, through its complex conveying path design, prevents dust from directly entering the interior of the terminal box body 1 while the air is flowing. Inside the curved groove 9, a filter screen 12 is also embedded. The filter screen 12 can effectively intercept and filter dust and other small particles in the air. After such dual treatment, the air will finally be discharged into the interior of the terminal box body 1 through the air outlet 10 set on the outer wall of the ventilation window 6, ensuring that the temperature inside the terminal box is maintained at a suitable level, thereby protecting the stable operation of the internal electronic equipment.

[0023] The working principle of this utility model is as follows: When using this utility model, the cooling fan 3 first starts working, and the generated airflow flows along the inlet pipe 13 at the bottom of the cooling fan 3 into the ventilation pipe 8, and then enters the curved groove 9 through the ventilation pipe 8. When the air flows inside the curved groove 9, it is filtered by the filter screen 12, and dust and fine particles in the air are effectively intercepted. The clean air continues to flow along the path of the curved groove 9, and finally is evenly discharged into the interior of the terminal box body 1 through the air outlet 10. This process not only achieves effective heat dissipation inside the terminal box, but also ensures the cleanliness of the internal environment and prevents dust from contaminating electronic components. At the same time, the heat dissipation window 2 set on the side of the terminal box body 1 also plays an auxiliary role in heat dissipation. It allows hot air to be discharged from the interior of the terminal box, further improving the heat dissipation efficiency. In addition, the double-layer mesh structure covering the inner wall of the heat dissipation window 2 effectively blocks the entry of external dust and fine particles, providing a good operating environment for the interior of the terminal box, realizing the dual functions of dust prevention and heat dissipation, and ensuring the stable operation of the outdoor terminal box of the substation.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
