Description

Technical Field

[0001] The invention relates to the technical field of rainproof structures of power boxes, and in particular to an outdoor drawer-type temporary rainproof power box and a rainproof method. Background Art

[0002] In the power system, temporary outdoor power supply is very frequent. Due to various emergencies outdoors, such as rain, it is necessary to suspend temporary power supply or provide rain protection for temporary power supply boxes. At present, temporary outdoor power supply boxes are mainly covered with plastic film rainproof cloth and fastened with ropes to prevent rain. This not only consumes manpower, material resources and time, but also has poor rainproof effect, and it is easy for rainwater to enter the power supply box and cause short circuit; even in substations, outgoing line fields and other places, strong winds blow away the rainproof cloth, resulting in exposed high-voltage wires, and phase-to-phase short circuits and other safety risks.

[0003] It can be seen that the current rainproof scheme for temporary power boxes still has room for improvement. It should be optimized and adjusted to improve the reliability of rainproofing, cope with complex and changeable weather conditions, and reduce the safety hazards of short circuits in the temporary power boxes. Therefore, it is necessary to adopt a more reasonable technical solution to solve the technical problems existing in the existing technology. Summary of the invention

[0004] The present invention proposes an outdoor drawer-type temporary rainproof power box and a rainproof method. By improving the structure of the outdoor temporary power box, the sealing performance of the temporary power box is improved through sealing strips, a transparent shell, and a door closing buckle, thereby ensuring that rainwater can be prevented from entering efficiently and with high quality. Through a desiccant cylinder and a thermometer and hygrometer, the temperature and humidity of the power box can be further monitored to prevent moisture from causing electrical accidents in the power box, thereby further ensuring the long-term safe and stable operation of the outdoor temporary power box.

[0005] In order to achieve the above purpose, the temporary rainproof power supply box disclosed in the present invention can adopt the following technical solutions:

[0006] An outdoor drawer-type temporary rainproof power box comprises an outer box body, an inner box body is slidably arranged inside the outer box body, the inner box body slides into the outer box body or slides out from the outer box body, and a sealed box door is arranged on the outer box body; a threading connection hole is arranged at the bottom of the outer box body, and an external power supply line enters through the threading connection hole and is connected to the incoming line jack of the inner box body; a temperature and humidity detection device and a drying device are also arranged in the outer box body.

[0007] The above disclosed temporary rainproof power supply box, by setting a structure that cooperates with the outer box and the inner box, can open the outer box when in use, connect the power supply through the inner box, and push the inner box out of the outer box when performing inspection and maintenance, so as to facilitate operation. When rainproof is required, push the inner box into the outer box, close the closed box door to prevent rain, and put the external power supply line into the outer box, so as to enhance the rainproof effect. The drying device arranged in the outer box is used to absorb moisture to avoid short circuit of the internal circuit caused by excessive humidity, and the temperature and humidity detection device is used to detect the temperature and humidity in the outer box, so as to facilitate monitoring and alarm.

[0008] Furthermore, in order to facilitate the sliding of the inner box in the outer box, a corresponding moving mechanism can be provided, and its structure is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: a slide rail structure is provided between the outer box and the inner box, and the inner box moves into or out of the outer box through the slide rail structure. When the above scheme is adopted, the sliding track includes a track and a track wheel, which are respectively provided on the outer box and the inner box.

[0009] Furthermore, the outer box body forms a closed waterproof space, which can provide a reliable waterproof effect after accommodating the inner box body. The specific sealing structure can be implemented by a variety of schemes, and its structure is not limited to a single one. It is optimized here and one of the feasible options is proposed: the sealed door of the outer box body is provided with a sealing structure, and the sealing structure includes a sealing strip and a sealing lock. When the sealed door is closed, the sealing strip seals the gap between the sealed door and the outer box body, and the sealing lock connects the sealed door and the outer box body tightly.

[0010] Furthermore, in some solutions, in order to facilitate viewing of the status of the internal box, the external box is optimized: a transparent observation area is provided on the sealed box door, or the sealed box door is made of transparent material. When such a solution is adopted, the connection status of the internal box can be directly seen from the outside.

[0011] Furthermore, the temperature and humidity detection device can adopt a variety of schemes, and its structure is not limited to a single one. Here, we optimize and propose one of the feasible options: the temperature and humidity detection device includes a thermometer and hygrometer, which is connected to the main controller; the thermometer and hygrometer is used to detect the temperature and humidity inside the outer box and transmit the detection results to the main controller. When the above scheme is adopted, after the main controller receives the monitoring data of the temperature and humidity sensor, it determines the temperature and humidity inside the outer box by analyzing the data, and thus determines whether to issue an alarm.

[0012] Furthermore, the drying device is used to absorb moisture inside the outer box to reduce the humidity inside the outer box, thereby keeping the inside of the outer box dry. Various solutions can be adopted: the drying device includes a drying cylinder, and a desiccant is arranged in the drying cylinder.

[0013] Furthermore, the inner box is used for connecting and supplying power to electrical equipment, and its structure is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the inner box is provided with a plurality of plug-in modules, and the plug-in modules include a plurality of sockets and a control switch; the control switch includes a two-hole straight-line socket, a three-hole shaped-pin socket, a two-hole aviation socket, and a three-hole aviation socket. When the above scheme is adopted, the inner box can be connected to and supply power to a variety of electrical equipment at the same time.

[0014] Furthermore, in order to facilitate wired power supply and realize wired power supply in various environments, an external power supply line is required to meet the plug-in power requirements, and optimization is performed here: a wire take-up device is arranged in the outer box body, and the wire take-up device includes a support foot and a wire take-up reel rotatably arranged on the support foot, and a crank is arranged on the wire take-up reel. When the crank is turned to drive the wire take-up reel to rotate, the external power supply line is wound onto the wire take-up reel or released from the wire take-up reel.

[0015] Further, in order to facilitate movement, an optimization is performed here: a walking mechanism is arranged below the outer box, and the walking mechanism includes legs, and the legs are provided with walking wheels and a brake structure below. When the above scheme is adopted, the legs are connected and fixed to the outer box, and the walking wheels below can be universal wheels.

[0016] Furthermore, when the temperature and humidity in the outer box are abnormal, a prompt is required. Here, an optimization is made and one of the feasible options is proposed: a warning light is also provided on the outer box, the warning light is connected to the main controller, and is turned on or off by the command of the main controller. When the above solution is adopted, the warning light can be an LED light, and a voice alarm can also be equipped.

[0017] The above content discloses a dust protection device, and the present invention also discloses a rain protection method, as follows:

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

[0019] Compared with the prior art, some beneficial effects of the technical solution disclosed in the present invention include:

[0020] The improved box structure of the present invention is simple and easy to use. It can provide sealed and waterproof protection for the temporary power box, avoiding circuit problems such as short circuit caused by rain on rainy days when the temporary power box is used outdoors, so that the power box can operate stably and reliably.
