Description

Technical Field

[0001] The utility model relates to the technical field of power distribution equipment, in particular to a DC power supply panel with a monitoring function. Background Art

[0002] A DC power panel, also known as a distribution box, is a component of the power supply system. It distributes electrical energy to the various auxiliary circuits and provides fuses or circuit breakers for each circuit in the system. Typically, the main switch and the nearest distribution panel also include one or more residual current devices or residual current circuit breakers with overcurrent protection. Power plants and substations now all use DC power for operating electrical power. DC power panels provide power for control loads, power loads, and DC emergency lighting loads, forming the foundation of modern power system control and protection.

[0003] DC power panels typically use their own batteries for power. Depending on the voltage requirements, multiple batteries may be connected in series. Therefore, the DC power panel's enclosure is typically configured as a multi-pass cabinet to house the batteries. When the DC power panel is operating, its power distribution equipment and batteries generate significant heat, causing the internal temperature to rise. Currently, some DC power panels lack internal temperature monitoring and are unable to adjust their heat dissipation capabilities. This can lead to internal overheating, resulting in equipment damage or even fire. Utility Model Content

It proposes a DC power supply screen that can monitor the internal temperature and adjust its heat dissipation intensity according to the monitoring results to ensure safe use.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A DC power supply screen with a monitoring function includes a power distribution cabinet and a storage rack; the storage rack is installed in the power distribution cabinet, the storage rack includes a layer plate, the layer plate includes multiple horizontal support plates, and a groove is formed on the side of the support plate away from the support surface; an auxiliary structure is installed in the power distribution cabinet, the auxiliary structure includes multiple adjustment rods located in each groove, heat sinks are rotatably installed on both sides of the groove, and multiple support rods are rotatably installed on the adjustment rods, and the support rods are respectively connected to the heat sinks located on both sides.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 3 In embodiment 1 of the present invention, a DC power supply screen with a monitoring function includes a power distribution cabinet 1 and a rack 4; the power distribution cabinet 1 is equipped with a rack 4, the rack 4 includes a layer plate 42, the layer plate 42 includes a plurality of transverse support plates 422, and a groove 4221 is formed on a side of the support plate 422 away from the support surface; the power distribution cabinet 1 is equipped with an auxiliary structure 2, the auxiliary structure 2 includes a plurality of adjustment rods 24 located in each groove 4221, and heat dissipation plates 25 are respectively rotatably installed on both sides of the groove 4221, and a plurality of support rods 26 are rotatably installed on the adjustment rod 24, and the support rods 26 are respectively connected to the heat dissipation plates 25 located on both sides.

[0022] This device is provided with a storage rack 4 in the power distribution cabinet 1 for placing batteries or other devices. The storage rack 4 is provided with multiple layers of laminates 42, and the laminate 42 is composed of multiple juxtaposed support plates 422. The support plate 422 is in a U-shape with an open bottom. An adjusting rod 24 is placed in the space of the groove 4221. At the same time, heat dissipation plates 25 are rotatably installed at both edges of the support plate 422. A support rod 26 is installed on the heat dissipation plate 25, and the support rod 26 is connected to the adjusting rod 24. When the adjusting rod 24 is lifted, restricted by the support rod 26, the heat dissipation plate 25 will retract inward and fold into the inside of the groove 4221, being invisible and beautiful without affecting normal use. When the temperature detector 31 detects that the internal temperature is too high and effective heat dissipation cannot be achieved through conventional heat dissipation methods, the adjusting rod 24 can be pressed down to drive the support rod 26 to open the two heat dissipation plates 25 outward. The support plate 422 and the heat dissipation plate 25 used in this device are both made of materials with good thermal conductivity, such as metal. Therefore, the heat of the battery placed on the support plate 422 can be effectively conducted, making the heat dissipation plate 25 also in a high-temperature state.

[0023] The air extraction fan 14 generates an air flow inside the power distribution cabinet 1 to achieve heat dissipation by using air flow heat exchange. When the heat dissipation plate 25 is opened, the air flow passes through the heat dissipation plate 25, which can带走 more heat, improving the overall heat dissipation capacity of the DC power supply panel to ensure the use safety of the hot standby.

[0024] This device can detect the internal temperature of the DC power supply panel and adjust the intensity of internal heat dissipation in real time according to the detection results, having the advantages of improving equipment safety and extending equipment service life.

[0025] As another embodiment of the present utility model, please refer to Figure 2 and Figure 3 , in Embodiment 2 of the present utility model, multiple groups of comb-shaped heat dissipation fins 251 are installed on the heat dissipation plate 25, and the heat dissipation fins 251 of the heat dissipation plates 25 on both sides of the groove 4221 are arranged crosswise. The heat dissipation fins 251 can increase the heat dissipation area. The air flow passes through the comb-shaped space between the heat dissipation fins 251, further enhancing the heat dissipation effect. And using the comb-shaped structure enables the two heat dissipation plates 25 to stagger when retracting, and both can obtain a larger width, improving the heat dissipation effect.

[0026] Please refer to Figures 1 to 3 , the laminate 42 includes two parallel mounting plates 421, the support plate 422 is connected between the mounting plates 421, and support columns 41 are respectively installed at the corners of the power distribution cabinet 1. The mounting plates 421 are fixedly connected to the support columns 41. The support columns 41 are used to provide support for each laminate 42, and the mounting plates 421 on both sides of the laminate 42 are used to form a connection between the support plate 422 and the support columns 41.

[0027] Please refer to Figure 2 and Figure 3 The mounting plate 421 is provided with a vertical slot 4211, through which both ends of the adjustment rod 24 extend. The adjustment rod 24 requires external force to be applied for adjustment, so the slot 4211 is required to allow the adjustment rod 24 to pass through. The vertical slot 4211 also limits the direction of movement of the adjustment rod 24, preventing the heat sinks 25 on both sides from opening asymmetrically.

[0028] See also Figure 1 The auxiliary structure 2 includes a connecting frame 23 located on both sides of the power distribution cabinet 1. The connecting frame 23 connects to each adjustment rod 24. A connecting plate 22 is mounted on the connecting frame 23, and a plurality of telescopic rods 21 connected to the power distribution cabinet 1 are mounted on the connecting plate 22. The telescopic rods 21 control the connecting frame 23 through the connecting plate 22, achieving the overall lifting and lowering of the connecting frame 23, thereby driving the movement of the adjustment rods 24. The telescopic rods 21 are actively telescopic and deformable structures and can use cylinders, hydraulic rods, electric push rods, or other retractable structures, such as a reciprocating structure with an eccentric wheel or a scissor mechanism.

[0029] See also Figure 1 The power distribution cabinet 1 is equipped with an equipment panel 15, on which are mounted multiple vacuum suction cups 3, each of which is equipped with a temperature probe 31. The position of each temperature probe 31 corresponds to the position of each shelf 42. The equipment panel 15 is used to mount the operating devices and display devices required for the DC power supply panel. The vacuum suction cups 3 secure the temperature probe 31 to the equipment panel 15. The position of the temperature probe 31 can be changed by moving the vacuum suction cups 3. The temperature probe 31 can detect air or directly detect the temperature of the battery or other equipment surface to obtain real-time temperature and adjust the heat dissipation intensity based on the obtained temperature information.

[0030] See also Figure 1 An exhaust fan 14 is installed inside the power distribution cabinet 1. The opening of the groove 4221 points toward the exhaust fan 14. An air outlet 13 is provided on the side of the power distribution cabinet 1 near the exhaust fan 14. Air inlets 11 are provided on both sides of the power distribution cabinet 1. The exhaust fan 14 generates negative pressure. After entering through the air inlet 11, the outside air flows through the batteries and the heat sink 25, and is finally discharged through the air outlet 13, removing a large amount of heat in the process.

[0031] See also Figure 1Adjustable feet 12 are installed on the outside of the distribution cabinet 1, and a cabinet door 16 is installed on the side of the distribution cabinet 1 away from the equipment panel 15. The exhaust fan 14 is generally installed at the bottom of the equipment. Therefore, the installation of adjustable feet 12 elevates the distribution cabinet 1, which can isolate moisture, keep the distribution cabinet 1 level, and leave space at the bottom for exhaust and heat dissipation. The cabinet door 16 can be opened to install and remove internal equipment and batteries.

[0032] The working principle of this utility model is:

[0033] This device is provided with a shelf 4 for placing batteries and various equipment in the distribution cabinet 1. The shelf 42 uses a support plate 422 with a groove 4221 at the bottom. An adjustment rod 24 that can be raised and lowered is placed in the groove 4221. At the same time, heat sinks 25 are rotatably connected on both sides of the groove 4221. The adjustment rod 24 uses a support rod 26 to connect each heat sink 25. An exhaust fan 14 is provided at the bottom of the distribution cabinet 1 to dissipate internal heat through airflow. At the same time, multiple temperature detectors 31 are installed in the distribution cabinet 1 to detect the internal temperature. When the equipment is overheated and cannot be fully dissipated by the exhaust fan 14, the adjustment rods 24 can be controlled to move downward, and the heat sink 25 originally stored in the groove 4221 can be expanded to both sides. The heat sink 25 and the support plate 422 are both made of materials with good thermal conductivity, so they can conduct high temperatures. The airflow passing through the heat sink 25 can take away more heat, thereby improving the efficiency of heat dissipation.
