Description

Technical Field

[0001] This utility model relates to the field of power supply switching technology, specifically a power supply switching device. Background Technology

[0002] Electricity is the primary energy source and driving force for modern industrial production.

Therefore, electricity is widely used in modern industry and daily life. Power supply refers to the safe, reliable, continuous, and qualified sale of electrical energy to a wide range of electricity customers through transmission and distribution equipment, meeting their needs for economic development and daily life. During the power supply process, to prevent losses caused by power outages, two circuits are often used to supply power to electrical equipment. In the event of an emergency power outage in the main circuit, the main circuit is disconnected by a power switching device, and the backup circuit supplies power to the electrical equipment.

[0003] For example, Chinese Patent No. CN219677799U discloses a power supply switching device, including a housing; the housing includes a casing, a cover plate, a connecting plate, and an electrical mounting plate. The front end of the casing is an open structure, and the electrical mounting plate is placed inside the casing.

[0004] However, the aforementioned power supply switching device cannot locate and directionally cool the high-temperature heat sources generated by the internal electronic components. As a result, the components will be in a high-temperature environment for a long time, which will accelerate the aging process of the components, reduce their performance and reliability, and shorten the service life of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a power supply switching device to solve the problem mentioned in the background art of not being able to locate and directionally supply air to dissipate the high-temperature heat source generated by the internal electronic components.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A power supply switching device includes: a power switching device body, one end of which is connected to and installed with a ring shell, and semi-circular guide rails are fixedly installed on the upper and lower surfaces of the ring shell. A heat dissipation mechanism is slidably installed between the two sets of semi-circular guide rails, so that the heat dissipation mechanism can blow cold air into different directions inside the power switching device body through the semi-circular guide rails.

[0008] Preferably, a ring sleeve is fixedly installed inside the ring shell, and an infrared sensor is inserted into the ring sleeve.

[0009] Preferably, the signal transmitting end of the infrared sensor is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electronic control end of the heat dissipation mechanism.

[0010] Preferably, the infrared detection element in the infrared sensor can receive infrared rays emitted by the electronic components inside the power switching device and convert them into electrical signals to be sent to the controller.

[0011] Preferably, the controller can determine the location and approximate temperature of the heat source generated by the electronic components within the power switching device by processing and analyzing these electrical signals.

[0012] Preferably, the infrared sensor and controller are Raytek MI 3 and RS485, respectively.

[0013] Preferably, the heat dissipation mechanism includes a cooling fan, one end of which is fixedly mounted with a connecting arm, which is slidably mounted on the outer surface of the semi-circular guide rail.

[0014] Preferably, a mounting plate is fixedly installed on the lower surface of the cooling fan, a motor is fixedly installed inside the mounting plate, a gear is fixedly installed at one end of the output shaft of the motor, the gear meshes with a gear ring, and the gear ring is fixedly installed on the inner ring surface of one set of semi-circular guide rails.

[0015] Preferably, the motor can drive the cooling fan to slide on the outer surface of the semi-circular guide rail by engaging the gear ring, thereby blowing cool air in different directions into the body of the power switching device.

[0016] Preferably, the motor is controlled by a controller.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Through the design of infrared sensors, semi-circular guide rails, gear rings, and heat dissipation mechanisms, when the heat dissipation mechanism blows air to cool the electronic components inside the power switching device, the infrared radiation generated by the electronic components is received by the infrared detection element in the infrared sensor and converted into electrical signals, which are then sent to the controller. By processing and analyzing these electrical signals, the controller can determine the location and approximate temperature of the heat source generated by the electronic components inside the power switching device. This allows the controller to control the heat dissipation mechanism to engage with the gear ring and slide on the outer surface of the semi-circular guide rail. It can control the air blowing end of the heat dissipation mechanism to perform directional airflow cooling operation relative to the high-temperature heat source. In this way, it can accurately control the air blowing end of the heat dissipation mechanism to be directed towards the high-temperature heat source for directional airflow cooling based on the location and temperature of the heat source generated by the electronic components. Compared with traditional fixed-position or indiscriminate cooling methods, this greatly improves the heat dissipation efficiency, can more effectively reduce the temperature of the heat-generating components, ensure the stable operation of the power switching device, and extend the service life of the electronic components.

[0019] 2. Through the design of the cooling fan, connecting arm, motor, and gears, the infrared sensor detects the high-temperature heat source and sends these electrical signals to the controller. The controller can then issue control commands to the motor to rotate forward or reverse the gears based on the determined heat source location information. This allows the gears to mesh with the ring gear, driving the cooling fan to slide along the outer surface of the semi-circular guide rail via the connecting arm. This ensures that the cooling fan's blowing end is accurately aligned with the high-temperature heat source, achieving directional airflow cooling. Once the high-temperature heat source is reduced to a set range, the motor drives the cooling fan back to its initial position facing the power switching device. This ensures that directional cooling only occurs when a high-temperature heat source is present, avoiding unnecessary energy consumption that may exist in traditional cooling methods. While ensuring cooling effect, it reduces energy consumption and improves energy utilization efficiency. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1-5 This embodiment provides the following technical solution:

[0028] like Figures 1-4 As shown, a power supply switching device includes: a power switching device body 1, an annular shell 2 connected to one end of the power switching device body 1, and semi-annular guide rails 203 fixedly installed on the upper and lower surfaces of the annular shell 2. A heat dissipation mechanism 3 is slidably installed between the two sets of semi-annular guide rails 203, so that the heat dissipation mechanism 3 can blow cold air into different directions inside the power switching device body 1 through the semi-annular guide rails 203.

[0029] An annular sleeve 201 is fixedly installed inside the annular shell 2, and an infrared sensor 202 is inserted into the annular sleeve 201.

[0030] The signal transmitting end of the infrared sensor 202 is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electrical control end of the heat dissipation mechanism 3.

[0031] The infrared detection element in the infrared sensor 202 can receive infrared rays emitted by the electronic components in the power switching device body 1 and convert them into electrical signals to be sent to the controller.

[0032] By processing and analyzing these electrical signals, the controller can determine the location and approximate temperature of the heat source generated by the electronic components inside the power switching device body 1.

[0033] The infrared sensor 202 and the controller are model numbers Raytek MI 3 and RS485, respectively.

[0034] Through the design of infrared sensor 202, semi-circular guide rail 203, gear ring 204, and heat dissipation mechanism 3, when the heat dissipation mechanism 3 blows air to dissipate heat from the electronic components inside the power switching device body 1, the infrared rays generated by the electronic components are received by the infrared detection element in infrared sensor 202 and converted into electrical signals and sent to the controller. The controller can determine the location and approximate temperature of the heat source generated by the electronic components inside the power switching device body 1 by processing and analyzing these electrical signals. The controller can then control the heat dissipation mechanism 3 to engage with the gear ring 204 and slide on the outer surface of the semi-circular guide rail 203. This allows the controller to control the blowing end of the heat dissipation mechanism 3 to perform directional airflow cooling operation relative to the high-temperature heat source. In this way, it can accurately control the blowing end of the heat dissipation mechanism 3 to be directed towards the high-temperature heat source for directional airflow cooling based on the location and temperature of the heat source generated by the electronic components. Compared with the traditional fixed position or indiscriminate heat dissipation method, this greatly improves the heat dissipation efficiency, can more effectively reduce the temperature of the heat-generating components, ensure the stable operation of the power switching device body 1, and extend the service life of the electronic components.

[0035] like Figure 5 As shown, the heat dissipation mechanism 3 includes a heat dissipation fan 301, and a connecting arm 302 is fixedly installed at one end of the heat dissipation fan 301. The connecting arm 302 is slidably installed on the outer surface of the semi-circular guide rail 203.

[0036] A mounting plate 303 is fixedly installed on the lower surface of the cooling fan 301. A motor 304 is fixedly installed inside the mounting plate 303. A gear 305 is fixedly installed on one end of the output shaft of the motor 304. The gear 305 meshes with a gear ring 204. The gear ring 204 is fixedly installed on the inner ring surface of one set of semi-circular guide rails 203.

[0037] The motor 304 drives the gear 305 to mesh with the gear ring 204, thereby driving the cooling fan 301 to slide on the outer surface of the semi-circular guide rail 203, thus blowing cold air in different directions into the power switching device body 1.

[0038] Motor 304 is controlled by a controller.

[0039] Through the design of the cooling fan 301, connecting arm 302, motor 304, and gear 305, the infrared sensor 202 detects a high-temperature heat source and sends these electrical signals to the controller. The controller can then issue control commands to the motor 304 to rotate forward or reverse the gear 305 based on the determined heat source location information. This allows the gear 305 to mesh with the gear ring 204, driving the cooling fan 301 to slide on the outer surface of the semi-circular guide rail 203 via the connecting arm 302. This ensures that the blowing end of the cooling fan 301 can accurately target the high-temperature heat source, achieving directional airflow cooling. Once the high-temperature heat source is reduced to a set range, the motor 304 drives the cooling fan 301 back to its initial position facing the power switching device body 1. This ensures that directional cooling only occurs when a high-temperature heat source is present, avoiding unnecessary energy consumption that may exist in traditional cooling methods. While ensuring the cooling effect, this reduces energy consumption and improves energy utilization efficiency.

[0040] Based on the above technical solution, the working steps of this solution are summarized as follows: When the cooling fan 301 blows air to cool the electronic components inside the power switching device body 1, the infrared rays generated by the electronic components are received by the infrared detection element in the infrared sensor 202 and converted into electrical signals and sent to the controller. By processing and analyzing these electrical signals, the controller can determine the location and approximate temperature of the heat source generated by the electronic components inside the power switching device body 1. The controller can then issue control commands to the motor 304 to rotate forward or reverse the gear 305. The gear 305 meshes with the gear ring 204, causing the cooling fan 301 to slide on the outer surface of the semi-circular guide rail 203 via the connecting arm 302. This allows the air blowing end of the cooling fan 301 to accurately target the high-temperature heat source, achieving directional airflow cooling operation. Once the high-temperature heat source is reduced to a set range, the motor 304 can drive the cooling fan 301 to return to its initial position facing the power switching device body 1, ensuring that directional cooling only occurs when a high-temperature heat source is present, thus avoiding unnecessary energy consumption that may exist in traditional cooling methods.

[0041] It is worth mentioning that the power switching device body 1 in this embodiment is the same as the power supply switching device disclosed in Chinese Patent No. CN219677799U, so it will not be described in detail here.

[0042] In summary, this device can precisely control the air blowing end of the heat dissipation mechanism 3 to direct airflow to the high-temperature heat source according to the location and temperature of the heat source generated by the electronic components. Compared with the traditional fixed position or indiscriminate heat dissipation method, it greatly improves the heat dissipation efficiency, can more effectively reduce the temperature of the heat-generating components, ensure the stable operation of the power switching device body 1, and extend the service life of the electronic components.
