Description

Technical Field

[0001] This utility model belongs to the field of power cabinet technology, specifically relating to an outdoor power cabinet. Background Technology

[0002] Outdoor power distribution cabinets are electrical devices used in outdoor environments to control, protect, and distribute power to power equipment in a power system. They feature a robust casing, typically made of stainless steel or high-strength aluminum alloy, effectively resisting corrosion from natural elements such as wind, sun, rain, and dust, with a protection rating generally reaching IP54 or higher.

[0003] When using power cabinets outdoors, during the rainy season, rain protection is usually achieved by installing a canopy on top of the power cabinet to increase its coverage area. While this method can provide rain protection, it often only protects the upper part of the power cabinet, leaving the bottom vulnerable to rain erosion. It is not an effective way to protect the top and sides of the power cabinet from rain. Utility Model Content

[0004] The purpose of this invention is to provide an outdoor power cabinet that can form an airflow barrier using the ejected airflow. When rainwater comes into contact with the airflow barrier, it can be directly blown away, preventing rainwater from falling directly onto the cabinet.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] An outdoor power cabinet includes a cabinet body, a protective door fitted to the front side wall of the cabinet body, a fan installed on the top surface of the inner cavity of the cabinet body, a shell fixedly connected to the top surface of the inner cavity of the cabinet body, the air inlet of the fan communicating with the shell, a plurality of plastic tubes fitted to the bottom surface of the shell, a plurality of evenly distributed through holes opened on the side wall of the plastic tubes, a support plate fixedly connected to the top surface of the cabinet body, an annular tube fixedly connected to the side wall of the support plate, the air outlet of the fan communicating with the annular tube, the annular tubes being rectangularly distributed, a plurality of first air holes opened on the side wall of the annular tubes away from the center of the cabinet body, the angle between the first air holes and the side wall of the cabinet body being 25°-45°.

[0007] Several joints are fixedly connected to the bottom surface of the inner cavity of the shell, and the plastic tube is connected to the shell through the joints.

[0008] A heating tube is fixedly connected to the inner wall of the housing.

[0009] A second air hole is provided on the side wall of the annular tube near the center of the cabinet, and the second air hole is inclined upward.

[0010] The plastic tube has an external thread near the top of its side wall, and the plastic tube is threadedly connected to the connector.

[0011] The shaped tube is made of copper or aluminum.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses an outdoor power cabinet that utilizes the cooperation between the cabinet body, fan, shell, and annular pipe. By setting an annular pipe at the top of the cabinet body, an airflow barrier is formed by the jetting airflow. When rainwater comes into contact with the airflow barrier, it can be directly blown away, preventing rainwater from falling directly onto the cabinet body, thus achieving a rainproof effect. In addition, during the snowy season, the airflow can be heated into hot airflow to quickly melt the snow and prevent snow from accumulating at the edge of the power cabinet.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] Example 1:

[0023] like Figures 1-5As shown, an outdoor power cabinet includes a cabinet body 1, a protective door 2 mounted on the front side wall of the cabinet body 1, a fan 3 installed on the top surface of the inner cavity of the cabinet body 1, a shell 4 fixedly connected to the top surface of the inner cavity of the cabinet body 1, the air inlet end of the fan 3 communicating with the shell 4, a number of plastic tubes 5 mounted on the bottom surface of the shell 4, a number of evenly distributed through holes 6 opened on the side wall of the plastic tubes 5, a support plate 7 fixedly connected to the top surface of the cabinet body 1, an annular pipe 8 fixedly connected to the side wall of the support plate 7, the air outlet end of the fan 3 communicating with the annular pipe 8, the annular pipe 8 being rectangularly distributed, a number of first air holes 9 opened on the side wall of the annular pipe 8 away from the center of the cabinet body 1, the angle between the first air holes 9 and the side wall of the cabinet body 1 being 25°-45°.

[0024] like Figure 2 and Figure 3 As shown, several connectors 10 are fixedly connected to the bottom surface of the inner cavity of the housing 4, and the plastic tube 5 is connected to the housing 4 through the connectors 10. The connectors 10 can be quick connectors or threaded sleeves, etc., to facilitate the connection of the plastic tube 5 with the housing 4, so as to facilitate the exhaust of airflow inside the cabinet 1. When the components inside the cabinet 1 are in operation, the heat generated can be discharged with the airflow, which can also play a role in heat dissipation.

[0025] like Figure 3 As shown, a second air hole 13 is provided on the side wall of the annular pipe 8 near the center of the cabinet 1, and the second air hole 13 is inclined upward. The airflow blown out by the first air hole 9 forms a square barrier on all four sides of the cabinet 1 for rain and snow protection, while the second air hole 13 blows out airflow at the top of the cabinet 1 in an inclined state to disperse the rain and snow falling on the upper side of the cabinet 1, thus achieving a highly efficient protection effect.

[0026] like Figure 4 As shown, the plastic tube 5 has an external thread 11 near the top of its side wall. The plastic tube 5 is threaded to the connector 10. The threaded connection makes it easy to connect the plastic tube 5 and the connector 10. On the other hand, when the number of plastic tubes 5 used is small, the connector 10 can be sealed with bolts.

[0027] The shaping tube 5 is made of copper or aluminum. Specifically, copper tubes have good flexibility and ductility, are easy to bend, and can maintain their shape after bending; aluminum tubes are lightweight, corrosion-resistant, have good bending performance, and are convenient for shaping and bending.

[0028] Example 2:

[0029] Based on Embodiment 1, this embodiment specifically discloses another way to use this solution:

[0030] like Figure 5 As shown, a heating tube 12 is fixedly connected to the inner wall of the housing 4.

[0031] Specifically, when cabinet 1 is used outdoors or in areas with rain and snow, the exhaust airflow can be heated by activating heating pipe 12, so that the exhaust airflow forms a hot airflow. When the snow encounters the hot airflow, it melts quickly, which can prevent snow accumulation around cabinet 1 and thus improve its practical performance.

[0032] The working principle of this utility model is as follows: First, select an appropriate number of plastic tubes 5 according to the requirements, and connect the plastic tubes 5 to the connector 10 through the external thread 11. Then, according to the arrangement of the components inside the cabinet 1, bend the plastic tubes 5 so that they are distributed inside the cabinet 1.

[0033] When it is necessary to perform rain protection on cabinet 1, the fan 3 is started. The fan 3 generates negative pressure to discharge the airflow inside cabinet 1, so that the airflow enters the annular pipe 8 and is discharged from the first air hole 9 and the second air hole 13 respectively. The airflow forms an airflow barrier. When rainwater comes into contact with the airflow barrier, it can be directly blown away, preventing rainwater from falling directly on cabinet 1, thus achieving the effect of rain protection. In addition, when used in the snowy season, the heating pipe 12 can be used to heat the airflow into hot airflow, which quickly melts the snow and prevents snow from accumulating on the edge of the power cabinet.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
