Description

Technical Field

[0001] The present invention discloses a dynamic sunshade device for outdoor radiators in a substation, which relates to the technical field of sunshading for outdoor radiators in a substation. Background Art

[0002] As a transfer station for voltage step-up and long-distance power transmission, a large amount of heat is generated by the transformer in a substation during operation, and heat dissipation needs to be carried out through radiators. When the substation radiator is in an outdoor environment, direct sunlight will cause a significant increase in the surface temperature of the radiator, affecting its heat dissipation effect and possibly causing equipment failures and shortening the service life of the equipment. Therefore, sunshading the outdoor radiator of the substation can reduce its surface temperature and improve the heat dissipation efficiency. At present, the sunshading effect of outdoor radiators in substations is mainly achieved through natural sunshading and artificial sunshading. Natural sunshading can use natural objects such as buildings and trees to shade the radiator. This method has a low cost, but the sunshading effect may be affected by environmental factors. Artificial sunshading achieves the sunshading effect by fixedly installing sunshade plates, sunshade awnings and other sunshading facilities. The sunshading effect is relatively good, but the fixedly installed sunshade plate also has certain limitations. The quality of the sunshading effect depends on the design of the sunshade plate and the installation position. During use, the sunshade plate cannot be dynamically adjusted with the sun's azimuth. Summary of the Invention

[0003] In order to overcome the defects that the sunshading effect of the sunshade device is unstable and the position cannot be dynamically adjusted during use, the present invention proposes a dynamic sunshade device for outdoor radiators in a substation, including a sunshade plate. The photosensitive sensor is fixedly installed on the sunshade plate and the bracket. The control board is fixedly installed on the bracket. The control board is located on one side of the photosensitive sensor on the bracket and is located below the sunshade plate. The solar panel is fixedly installed on the sunshade plate. The solar panel is electrically connected to the storage battery. The storage battery is fixedly installed on the control board.

[0004] Specifically, a servo bracket is fixedly installed below the sunshade plate. The bracket serves as the basis for supporting the stable operation of the servo. There are screw holes on both sides of the servo bracket. The servo is firmly fixedly installed on the servo bracket through the screw holes. The servo base has an installation interface matching the bracket and is fixedly installed on the bracket.

[0005] Specifically, the control board is fixedly installed on the bracket structure of the sunshade plate system. The control board is located below the sunshade plate and is connected to the servo, the motor and the photosensitive sensor.

[0006] Specifically, the photosensitive sensor is fixedly installed on the sunshade plate. The photosensitive sensor is located at the center of the sunshade plate. There is a photosensitive resistor in each of the four directions on the sensor.

[0007] To solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A dynamic sunshade device for outdoor radiators in a substation. The main body of the sunshade board is supported by a bracket. The left end of the bracket is connected to the sunshade board by a servo motor, and the tilt angle of the sunshade board is controlled by the servo motor. The right end of the bracket is connected to a motor, and by controlling the rotation of the motor to rotate the bracket, the sunshade board can cover the area directly irradiated by the sun above the radiator. After the sensor receives the sunlight irradiation, it sends a signal to the control board. The control board judges the area and angle with the maximum solar radiation, and sends rotation and tilt signals to the motor and the servo motor. The sunshade board can rotate with the position of direct sunlight, dynamically ensuring the best sunshade effect and minimizing the temperature rise of the radiator caused by direct sunlight.

[0009] For the above-mentioned dynamic sunshade device for outdoor radiators in a substation, the servo motor is fixed on the servo motor bracket below the sunshade board, and the sensor is a photosensitive sensor.

[0010] For the above-mentioned dynamic sunshade device for outdoor radiators in a substation, the servo motor, the motor, and the sensor are all controlled by a control board.

[0011] The beneficial effect of the present invention is that the sunshade board of this device uses a method of horizontal rotation and adjustment of the tilt angle for sunshading, effectively preventing the poor sunshade effect caused by the different positions of direct sunlight at different times in traditional sunshade boards, and ensuring that the outdoor radiator in the substation will not have its temperature rise due to direct sunlight. And the solar panel on the sunshade board can absorb solar energy to provide electrical energy for the device, which is more energy-saving and environmentally friendly.

[0017] During specific implementation, the photosensitive sensor 302 is irradiated by sunlight, the photoresistor changes, and the voltage values in all directions are transmitted back to the control board 7. The control board 7 determines the sunlight irradiation intensity based on the magnitude of the voltage values, sends a signal to the motor 8, and controls the motor 8 to rotate the bracket 6 to turn the sunshade 1 to the direction with the strongest sunlight. Then, the photosensitive sensor 301 transmits the voltage change back to the control board 7, and the control board 7 controls the steering gear 4 to make the sunshade 1 find the angle with the maximum sunlight, thus achieving the best sunshading effect.

[0018] It should be noted that a solar panel 2 is provided on the sunshade 1 in the present invention, which is used to collect solar energy and transmit the converted electric energy to the control board 7 for the use of the entire device.

[0019] In the present invention, the control board 7 is located below the sunshade 1, ensuring that the control board 7 can work in a relatively safe environment free from the influence of direct sunlight, thereby extending its service life and reducing the performance degradation caused by high temperature. The photosensitive sensor 301 is located at the center of the sunshade 1 and rotates together with the sunshade, and the photosensitive sensor 302 is fixedly installed on the bracket 6.
