Description

Technical Field

[0001] This utility model relates to the technical field of rainproof structure for power supply boxes, specifically to an outdoor drawer-type temporary rainproof power supply box. Background Technology

[0002] In power systems, temporary outdoor power supply is a very frequent occurrence. Due to various unforeseen circumstances outdoors, such as rain, it is necessary to suspend temporary power supply or provide rain protection for temporary power boxes. Currently, outdoor temporary power boxes are mainly covered with plastic film tarpaulins and secured with ropes for rain protection. This method is not only labor-intensive, resource-intensive, and time-consuming, but also has poor rain protection effectiveness, making it easy for rainwater to enter the power box and cause short circuits. In some substations and outgoing line sites, strong winds can blow away the tarpaulins, exposing high-voltage conductors and causing phase-to-phase short circuits and other safety risks.

[0003] It is evident that the current rainproofing solutions for temporary power supply boxes have room for improvement and should be optimized to enhance their reliability, enabling them to cope with complex and changing weather conditions and reduce the safety hazards of short circuits at the temporary power supply box. Therefore, a more reasonable technical solution is needed to address the technical problems existing in the current technology. Utility Model Content

[0004] This utility model proposes an outdoor drawer-type temporary rainproof power supply box. By improving the structure of the outdoor temporary power supply box, the sealing performance of the temporary power supply box is improved through sealing strips, transparent shells, and door latches, ensuring efficient and high-quality prevention of rainwater ingress. Through desiccant cartridges and thermometers and hygrometers, the temperature and humidity of the power supply box can be further monitored to prevent electrical accidents caused by moisture, and further ensure the long-term safe and stable operation of the outdoor temporary power supply box.

[0005] To achieve the above objectives, the temporary rainproof power supply box disclosed in this utility model can adopt the following technical solution:

[0006] An outdoor drawer-type temporary rainproof power supply box includes an outer casing, an inner casing that slides inside the outer casing, and the inner casing slides into or out of the outer casing. The outer casing has a sealed door. The bottom of the outer casing has a wiring connection hole through which an external power supply line enters and connects to the inlet socket of the inner casing. The outer casing also contains a temperature and humidity detection device and a drying device.

[0007] The aforementioned temporary rainproof power supply box features an outer and inner casing that work together. In use, the outer casing can be opened, and power connections can be made through the inner casing. For maintenance and repair, the inner casing can be pushed out of the outer casing for easy operation. When rain protection is needed, the inner casing is pushed into the outer casing, the door is closed, and the external power supply cable is retracted into the outer casing, thus enhancing the rainproof effect. A drying device inside the outer casing absorbs moisture to prevent short circuits caused by excessive humidity, while a temperature and humidity detection device monitors the temperature and humidity inside the outer casing for monitoring and alarm functions.

[0008] Furthermore, to facilitate the sliding of the inner casing within the outer casing, a corresponding moving mechanism can be provided. Its structure is not limited to a single specific mechanism; here, an optimization is proposed, and one feasible option is suggested: a slide rail structure is provided between the outer and inner casings, allowing the inner casing to move into or out of the outer casing via the slide rail structure. When adopting the above solution, the sliding rail includes a track and track wheels, respectively positioned on the outer and inner casings.

[0009] Furthermore, the outer casing forms a closed, waterproof space, providing reliable waterproofing after accommodating the inner casing. The specific sealing structure can be implemented using various methods, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the outer casing has a sealing structure at the sealed door, which includes a sealing strip and a sealing latch. When the sealed door is closed, the sealing strip seals the gap between the sealed door and the outer casing, and the sealing latch connects and fastens the sealed door to the outer casing.

[0010] Furthermore, in some designs, the outer casing is optimized to facilitate viewing the internal casing's condition: the sealed door is equipped with a transparent observation area, or the sealed door is made of transparent material. With such a design, the connections of the internal casing can be directly observed from the outside.

[0011] Furthermore, the temperature and humidity detection device can adopt various schemes, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the temperature and humidity detection device includes a thermometer and hygrometer connected to the main controller; the thermometer and hygrometer are used to detect the temperature and humidity inside the outer casing and transmit the detection results to the main controller. When adopting the above scheme, after receiving the monitoring data from the temperature and humidity sensor, the main controller analyzes the data to determine the temperature and humidity conditions inside the outer casing, thereby determining whether to issue an alarm.

[0012] Furthermore, the drying device is used to absorb moisture inside the outer casing, reduce the humidity inside the outer casing, and thus keep the inside of the outer casing dry. Various methods can be adopted: the drying device includes a drying cylinder, and a desiccant is placed inside the drying cylinder.

[0013] Furthermore, the inner enclosure is used for connecting and supplying power to electrical equipment. Its structure is not uniquely limited; here, an optimization is proposed, and one feasible option is suggested: the inner enclosure is equipped with several plug-in modules, each including several sockets and control switches; the control switches include two-hole straight sockets, three-hole triangular sockets, two-hole aviation sockets, and three-hole aviation sockets. Using this solution, the inner enclosure can simultaneously connect and supply power to multiple electrical devices.

[0014] Furthermore, in order to facilitate power supply and enable power supply in various environments, the external power supply line needs to meet the plug-in power requirements. Here, an optimization is made: a take-up device is installed inside the outer casing. The take-up device includes a support leg and a take-up drum rotatably mounted on the support leg. A crank is installed on the take-up drum. When the crank is turned to drive the take-up drum to rotate, the external power supply line is wound into the take-up drum or released from the take-up drum.

[0015] Furthermore, for ease of movement, the following optimization is made: a walking mechanism is provided below the outer casing, the walking mechanism including outriggers, and wheels and brakes are installed on the lowered outriggers. With the above solution, the outriggers are fixedly connected to the outer casing, and the wheels can be swivel casters.

[0016] Furthermore, when the temperature and humidity inside the outer casing are abnormal, a warning signal is required. Here, we propose an optimization and one feasible option: The outer casing is also equipped with a warning light, which is connected to the main controller and turned on or off according to the controller's commands. When using this solution, the warning light can be an LED light, and a voice alarm can also be added.

[0017] The above-mentioned dustproof protection device is disclosed. This utility model also discloses a rainproof method, as follows:

[0018] A method for protecting an outdoor drawer-type temporary rainproof power supply box from rain, using the rainproof power supply box described above.

[0020] The improved enclosure structure of this utility model is simple and easy to use. It can provide sealed and waterproof protection for temporary power boxes, preventing short circuits and other circuit problems caused by rainwater when used outdoors, thus enabling the power box to operate stably and reliably.
