Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, and in particular to a high-efficiency and energy-saving prefabricated substation. Background Technology

[0002] Prefabricated box-type substations are mobile substation devices that integrate high-voltage switchgear, transformers, and low-voltage switchgear, and are assembled in the manufacturing plant. Due to their small size, simple on-site construction, no need for building, easy operation, and high reliability, these devices have an extremely wide range of applications.

[0003] In existing technologies, such as Chinese patent CN218732718U, a high-efficiency energy-saving prefabricated substation includes an energy-saving mechanism comprising a base plate, a housing, a motor, fan blades, and an exhaust fan. The top of the base plate movably contacts the housing, which has openings on both the front and bottom sides. This invention uses a motor to drive a circular plate to rotate, which in turn drives a movable plate via a connecting rod. The movable plate moves two cylinders, compressing springs. Continuous motor operation drives the fan blades to move left and right in a cyclical manner. Hot air is discharged through heat dissipation holes into the gap between the housing and the U-shaped plate, and then expelled by the exhaust fan. This prevents convection between the internal and external air of the prefabricated substation in cold weather, thus preventing increased humidity inside the substation and avoiding equipment malfunctions due to increased humidity. This reduces maintenance costs and achieves high energy efficiency.

[0004] In the aforementioned patent, a circular plate is rotated by a motor, and then the circular plate moves a movable plate via a connecting rod. The movable plate moves two cylinders to compress a spring. The continuous operation of the motor drives the fan blades to move left and right in a circular motion, achieving a uniform heat dissipation effect. However, a U-shaped plate is fixedly installed on the outside of the energy-saving mechanism, and the motor driving the fan is located on the inside of the energy-saving mechanism. When the fan operates for a long time, it will also emit a high temperature, which will increase the internal temperature of the prefabricated substation. The exhaust fan and drive motor need to increase their power to discharge the high-temperature gas inside, resulting in a large power consumption and poor energy-saving effect. Therefore, we propose a high-efficiency energy-saving prefabricated substation. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, when the fan is working for a long time, it will also emit a high temperature, which will increase the internal temperature of the prefabricated substation. This requires the exhaust fan and drive motor to increase their power to discharge the high-temperature gas inside, resulting in large power consumption and poor energy saving effect. Therefore, this invention proposes a high-efficiency and energy-saving prefabricated substation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency and energy-saving prefabricated substation, comprising: a base plate, a housing fixedly connected to the top of the base plate, and a heat dissipation assembly fixedly connected to the top of the housing; the heat dissipation assembly includes a mounting frame, multiple filter holes evenly opened on the outer surfaces of both sides of the mounting frame, a fixing bracket fixedly connected to the top of the mounting frame, a motor fixedly connected to the top of the fixing bracket, the output end of the motor rotatably penetrating through the outer surface of the fixing bracket, a driving gear fixedly connected to the output end of the motor, driven gears symmetrically arranged on the outer surface of the driving gear, rotating rods fixedly connected to the inner surfaces of the two driven gears, and multiple fan blades fixedly connected at equal intervals on the outer surfaces of the two rotating rods.

[0007] Preferably, the outer surface of the rotating rod rotates through the top of the mounting frame and extends downwards, and the outer surface of the driving gear meshes and rotates with the outer surface of the driven gear.

[0008] Preferably, a fixing plate is fixedly connected to the inner surface of the mounting frame near the bottom, and the inner surface of the fixing plate is rotatably connected to the outer surface of the rotating rod.

[0009] Preferably, the mounting frame is fixedly connected to the top of the box, and the mounting frame is in communication with the box.

[0010] Preferably, multiple heat dissipation holes are evenly opened on both outer surfaces of the box, and protective shells are fixedly connected to both outer surfaces of the box near the multiple heat dissipation holes.

[0011] Preferably, a mounting plate is provided on the top of the housing, and a solar panel is provided on the top of the mounting plate.

[0012] Preferably, the bottom of the mounting plate is fixedly connected to support rods near the four corners, and the top of the multiple support rods is fixedly connected to the mounting plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, during use, the drive motor is installed on the top of the housing. The output end of the motor drives the active gear to rotate, which in turn drives two driven gears. This causes the two rotating rods to rotate at high speed, driving two sets of multiple fan blades to rotate synchronously. When this causes the mounting frame to generate negative pressure, external cold air is drawn in through multiple filter holes and blown downwards, accelerating the airflow speed inside the substation. This forces the hot air to be discharged from multiple heat dissipation holes on both sides, thus achieving heat dissipation and preventing the substation from being in a continuously high-temperature state, which would increase energy consumption. This solves the problem in the background technology where, when the motor-driven fan works inside the energy-saving structure, it generates a high temperature due to continuous operation, requiring the exhaust fan and drive motor to increase their power to discharge the high-temperature gas inside, resulting in high power consumption and poor energy-saving effect.

[0015] 2. In this utility model, during use, an installation plate is set on the top of the box, and the installation plate is fixedly connected to the top of the box by multiple support rods. The solar panel set on the top starts to work under the illumination of sunlight, converting solar energy into electrical energy. When the motor is electrically connected to the solar panel, it can work through the current generated by the solar panel, which further improves the energy-saving effect of the prefabricated substation.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-5 As shown, this utility model provides a high-efficiency and energy-saving prefabricated substation, including: a base plate 1, a housing 2 fixedly connected to the top of the base plate 1, and a heat dissipation assembly 4 fixedly connected to the top of the housing 2; the heat dissipation assembly 4 includes a mounting frame 401, with multiple filter holes 409 evenly distributed on the outer surfaces of both sides of the mounting frame 401, a fixing bracket 402 fixedly connected to the top of the mounting frame 401, a motor 403 fixedly connected to the top of the fixing bracket 402, the output end of the motor 403 rotating through the outer surface of the fixing bracket 402, a driving gear 404 fixedly connected to the output end of the motor 403, driven gears 405 symmetrically arranged on the outer surface of the driving gear 404, and the inner surfaces of the two driven gears 405 being fixedly connected. A rotating rod 406 is connected to the outer surface of both rotating rods 406, and multiple fan blades 407 are fixedly connected at equal intervals. The outer surface of the rotating rod 406 rotates through the top of the mounting frame 401 and extends downward. The outer surface of the driving gear 404 meshes with the outer surface of the driven gear 405 and is rotatably connected. A fixing plate 408 is fixedly connected to the inner surface of the mounting frame 401 near the bottom. The inner surface of the fixing plate 408 is rotatably connected to the outer surface of the rotating rod 406. The mounting frame 401 is fixedly connected to the top of the box 2 and is connected to the box 2. Multiple heat dissipation holes 8 are evenly opened on the outer surfaces of both sides of the box 2. Baffles 3 are fixedly connected to the outer surfaces of both sides of the box 2 near the multiple heat dissipation holes 8.

[0025] The overall effect of Embodiment 1 is that, when used in a high-efficiency, energy-saving prefabricated substation, it is first fixedly installed at the mounting point via the base plate 1, and the transformer is fixedly installed inside the enclosure 2. The motor 403, fixedly mounted on top of the mounting frame 402, is started. When the output end of the motor 403 drives the drive gear 404 to rotate, the drive gear 404 synchronously meshes with and rotates two driven gears 405, causing the two rotating rods 406 to rotate at high speed between the inner walls of the mounting frame 401 and the fixing plate 408. This, in turn, drives two sets of multiple fan blades 407 to rotate, generating a negative pressure inside the mounting frame 401. Under negative pressure, external air enters the mounting frame 401 through multiple filter holes 409. The multiple filter holes 409 play a filtering role, preventing impurities in the external air from entering. Under the action of multiple fan blades 407, the external cold air blows from top to bottom on the internal structure of the substation, accelerating the flow speed of the airflow inside the substation, forcing the hot airflow to be discharged from multiple heat dissipation holes 8 on both sides. Under the guiding action of the baffle 3, the hot airflow will be discharged downward along the inner wall of the baffle 3. The baffle 3 plays a dustproof role, preventing floating dust in the air from entering the housing 2 through multiple heat dissipation holes 8.

[0026] Example 2: Figures 1-5 As shown, a mounting plate 5 is installed on the top of the housing 2, a solar panel 7 is installed on the top of the mounting plate 5, and support rods 6 are fixedly connected to the bottom of the mounting plate 5 near the four corners. The top of the multiple support rods 6 are all fixedly connected to the mounting plate 5.

[0027] The effect achieved by the entire embodiment 2 is that, when used under sufficient sunlight, by setting an installation plate 5 on the top of the housing 2, and fixing the installation plate 5 to the top of the housing 2 through multiple support rods 6, the solar panel 7 set on the top of it starts to work under the illumination of sunlight, converting solar energy into electrical energy, so that when the motor 403 is electrically connected to the solar panel 7, it can work through the current generated by the solar panel 7, further improving the energy-saving effect of the prefabricated substation.

[0028] Working Principle: In the high-efficiency energy-saving prefabricated substation, the transformer is first fixedly installed at the mounting point via the base plate 1. The transformer is fixedly installed inside the enclosure 2. The motor 403, fixedly mounted on top of the mounting frame 402, is started. When the output of the motor 403 drives the drive gear 404 to rotate, the drive gear 404 simultaneously meshes with and rotates two driven gears 405, causing the two rotating rods 406 to rotate at high speed between the inner walls of the mounting frame 401 and the fixing plate 408. This, in turn, drives two sets of multiple fan blades 407 to rotate, creating a negative pressure inside the mounting frame 401. Under this negative pressure, external air enters the mounting frame 401 through multiple filter holes 409. These filter holes 409 filter impurities from the external air, preventing them from entering. The external cold air is then cooled by the action of the multiple fan blades 407. The airflow is blown from top to bottom through the internal structure of the substation, accelerating the airflow speed inside the substation and forcing the hot airflow to be discharged from multiple heat dissipation holes 8 on both sides. Under the guidance of the baffle 3, the hot airflow will be discharged downward along the inner wall of the baffle 3. The baffle 3 plays a dustproof role, preventing airborne dust from entering the box 2 through multiple heat dissipation holes 8. When used in sunlight, the mounting plate 5 is installed on the top of the box 2. The mounting plate 5 is fixedly connected to the top of the box 2 by multiple support rods 6. The solar panel 7 installed on the top starts to work under the sunlight, converting solar energy into electrical energy. When the motor 403 is electrically connected to the solar panel 7, it can work through the current generated by the solar panel 7, further improving the energy-saving effect of the prefabricated substation.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
